The History of the Imperial Forums and the Roman Forum: Two Thousand Years of Power

Few places on earth condense so much history into such a small space. The Imperial Forums and the Roman Forum recount, stone by stone, the entire arc of Roman civilisation: from the founding of the city on the Palatine Hill, through the Republic and the Empire, to the slow medieval dissolution. Visiting this archaeological complex means walking literally upon the accumulated layers of two thousand years of Western history.

The Roman Forum — the Forum Romanum — is the oldest. Its origins date to the 7th–6th century BC, when the valley between the Capitoline, the Palatine and the Quirinal hills was drained and transformed into a public square. For centuries it was the absolute centre of Roman life: here popular assemblies were held, justice was administered, military triumphs celebrated, and politics debated. The expression "going to the Forum" meant for a Roman what "going into town" means for us today.

From the Roman Forum to the Imperial Forums: The Expansion of Power

As Rome grew in population and political weight, the Roman Forum soon proved insufficient. It was Julius Caesar, in 54 BC, who inaugurated the era of the Imperial Forums by constructing the Forum of Caesar, the first in a series of monumental spaces designed to glorify the personal power of the emperors. After him, Augustus, Vespasian, Nerva and Trajan — each with increasingly grandiose ambitions — progressively expanded the forum complex to the north-east, creating what has become one of the most extraordinary concentrations of monumental architecture in the ancient world.

  • Forum of Caesar (54–46 BC): the first of the imperial forums, with the Temple of Venus Genetrix, mythological mother of the gens Iulia
  • Forum of Augustus (2 BC): the most elaborately ideological, with the Temple of Mars Ultor and statues of Roman heroes
  • Forum of Vespasian or Forum of Peace (75 AD): built to celebrate the victory in the Jewish War and to house the treasures of the Temple of Jerusalem
  • Forum of Nerva (97 AD): also known as the "Transitory Forum" for its connecting function, with the Temple of Minerva
  • Forum of Trajan (112 AD): the most grandiose of all, with Trajan's Column, the Markets of Trajan, the Basilica Ulpia and two libraries

Together with the Roman Forum, these six spaces form an urban system unique in the world: approximately 2.5 square kilometres of monumental public architecture, whose construction spanned almost two centuries and involved tens of thousands of workers.

Decline and Rediscovery

With the fall of the Western Roman Empire in 476 AD and the subsequent barbarian invasions, the Forums began a long decline. In the Middle Ages they became quarries for building materials: marble columns ended up in churches, blocks of travertine in palaces. The Roman Forum was known to medieval Romans as Campo Vaccino — the field of cattle — because it had been reduced to pastureland. The Via Sacra was buried under metres of debris, and the columns of temples barely emerged from the earth like relics of a forgotten world.

Systematic excavations began in the 18th and 19th centuries, first during the Napoleonic period and then under the Kingdom of Italy. Mussolini, in 1932, had the Via dei Fori Imperiali built — demolishing entire medieval and Renaissance districts — to link Piazza Venezia to the Colosseum for the regime's rallies. A town-planning decision that historians and urbanists debate to this day, but one that has made the Forums accessible and visible to millions of visitors.

Excavations continue even now: it is estimated that only 40–50% of the site has been brought to light. Beneath the Via dei Fori Imperiali, beneath the pavements and surrounding car parks, intact portions of Roman buildings still lie waiting to be discovered.

What to See in the Roman Forum: The 10 Monuments Not to Miss

The Roman Forum is one of the richest and most complex sites in all of Rome. Without a map or guide it is easy to feel disoriented in the face of what may seem like interchangeable expanses of ruins. Here are the principal monuments most worthy of attention, in order of historical importance and visual impact.

1. The Via Sacra

The cardo maximus of the Roman Forum, the most sacred street in Rome. Walking along it means treading the same axis that was traversed by triumphators and emperors for nearly a thousand years. It was the primary axis around which all public life in the forum was organised. Today it is still paved with original basalt stones — authentic Roman paving worn smooth by centuries of footsteps.

2. The Temple of Saturn

Founded in 498 BC and rebuilt several times, the Temple of Saturn is one of the most iconic symbols of the Roman Forum. Its eight surviving Corinthian columns dominate the western end of the forum visually. The temple housed the Roman state treasury — the aerarium — and was the site of the Saturnalia festivals, the Roman equivalent of Christmas.

3. The Basilica Julia

Begun by Julius Caesar in 54 BC and completed by Augustus, the Basilica Julia was one of the largest buildings in the forum: 101 metres long by 49 metres wide. It housed law courts and commercial activities. Today only the foundations and a few columns remain, but its vastness is still perceptible. The floor still bears incised boards of Roman games, scratched by people waiting for hearings.

4. The Temple of Julius Caesar

Built by Augustus in 29 BC on the spot where Caesar was cremated, this temple is historically extraordinary: it was the first Roman temple dedicated to a deified mortal. An altar inside marked the exact location of the funeral pyre. Romans brought flowers to that spot — and, remarkably, the tradition survives today: visitors from all over the world continue to leave fresh flowers on the temple podium.

5. The Arch of Septimius Severus

Erected in 203 AD to celebrate victories over the Parthians, this three-bay triumphal arch is one of the most imposing in the forum. Nearly 21 metres high, it is decorated with reliefs depicting the emperor's military campaigns. It stands at the north-western end of the forum, facing the Curia.

6. The Curia Julia (the Roman Senate)

One of the best-preserved buildings in the entire Roman Forum. The Curia is where the Senate of Rome met: the present building dates to 283 AD but follows the plan of the curia rebuilt by Augustus after a fire. Inside, the Plutei of Trajan — an important marble sculpture depicting scenes of Roman public life — is on display.

7. The Temple of Vesta and the House of the Vestals

The small circular Temple of Vesta housed the sacred fire which — according to tradition — must never be extinguished, because Rome's survival depended on its flame. The Vestals, six priestesses who served here for thirty years, were among the most respected figures in Roman society. Adjacent to the temple is the House of the Vestals, with its courtyards, pools and statues of the priestesses.

8. The Arch of Titus

Built in 81 AD to celebrate the conquest of Jerusalem and the destruction of the Temple in 70 AD, the Arch of Titus stands at the eastern end of the Via Sacra. Its internal reliefs — showing the Menorah and the treasures of the Temple being carried to Rome — are among the most precise and historically significant works in all Roman art. For many centuries, the Jews of Rome refused to walk beneath this arch.

9. The Palatine Hill

Technically the Palatine is not part of the Roman Forum, but it is included in the same admission and accessed directly from the site. The Palatine Hill is the cradle of Rome: here, according to tradition, Romulus founded the city in the 8th century BC. In the Imperial period it became the residential quarter of the emperors — the word "palace" itself derives from "Palatium". The ruins of the imperial residences (Domus Augustana, Domus Flavia, Villa of Livia) offer a breathtaking setting.

10. The Temple of the Dioscuri

The three Corinthian columns of the Temple of Castor and Pollux are one of the most photographed views in the Roman Forum. The temple was built in the 5th century BC to give thanks to the divine twins who, according to legend, fought alongside the Romans at the Battle of Lake Regillus. The surviving columns date to a 1st-century AD restoration and are among the defining images of all Roman archaeology.

The Imperial Forums: The Complex from Caesar to Trajan

The Imperial Forums extend along the Via dei Fori Imperiali, the great thoroughfare linking Piazza Venezia to the Colosseum. Unlike the Roman Forum — a living, multifunctional place — the Imperial Forums were monumental spaces designed to glorify imperial power: colossal piazzas, majestic temples, heroic statues. Each forum reflects the personality and ambitions of the emperor who commissioned it.

The Forum of Caesar: The Pioneer

The Forum of Caesar was the first. Built between 54 and 46 BC with the spoils of the Gallic Wars, it was dominated by the Temple of Venus Genetrix, the goddess Caesar claimed as his divine ancestor. Today the column bases of the portico, remains of the temple, and a series of tabernae are visible. It is one of the Imperial Forum sites accessible via dedicated routes managed by Roma Capitale.

The Forum of Augustus: The Most Symbolic

The Forum of Augustus is the most ideologically charged. Built to fulfil a vow made by Octavian before the Battle of Philippi (42 BC), it was dominated by the Temple of Mars Ultor — Mars the Avenger. The temple was the place where Roman generals gathered before setting out to war and returned after victory. The enormous surviving columns of the temple, the perimeter wall nearly 30 metres high built to protect the forum from fires in the Suburra district, and the statues of Roman heroes in the lateral exedrae make this one of the most evocative settings in the entire forum complex.

The Forum of Vespasian (Forum of Peace)

Built between 71 and 75 AD by Vespasian to celebrate the victory in the Jewish War and the destruction of the Temple of Jerusalem, the Forum of Peace housed the plundered treasures: the Menorah, the table of showbread and the silver trumpets. It was also a museum before the term existed: Greek artworks brought to Rome decorated the portico. It preserves one of the most important cartographic testimonies of antiquity: the Forma Urbis Romae, a highly detailed marble map of Rome from the 3rd century AD, was discovered embedded in a corridor of the forum.

The Forum of Nerva

The Forum of Nerva — also called the "Transitory Forum" for its connecting function between the Roman Forum and the Forum of Augustus — is the least visited of the complex. The two columns with a frieze from the Temple of Minerva, patroness of arts and crafts, are still visible. The temple itself was demolished in 1606 by Pope Paul V to obtain building materials for the Acqua Paola fountain: an irreparable loss that serves as a reminder of how the Roman heritage continued to be pillaged even in later centuries.

The Forum of Trajan: The Masterpiece

The Forum of Trajan is, without question, the most grandiose of the imperial forums. Inaugurated in 112 AD by Emperor Trajan, it was designed by the Syrian architect Apollodorus of Damascus and built with the spoils of the conquest of Dacia (modern Romania). The complex included a vast piazza with an equestrian statue of Trajan, the Basilica Ulpia — the largest basilica in Rome, with five naves — two twin libraries (one Greek and one Latin), the celebrated Trajan's Column, and the Markets of Trajan on the Quirinal slope.

Trajan's Column is the jewel of the complex: nearly 40 metres high (30 metres of shaft plus 9 of base), it is wrapped in a spiral frieze 200 metres long recounting, with extraordinary precision, Trajan's two Dacian Wars. Approximately 2,500 human figures sculpted with rare artistic quality make the column the most important visual document of the Roman army in action. It was originally surmounted by a gilded statue of Trajan, replaced in 1587 by a bronze statue of Saint Peter.

The Ideal Route: How to Visit the Imperial Forums, the Roman Forum and the Colosseum in One Day

One of the most common dilemmas for those planning a visit to the forum area is: where to begin? The Colosseum is the most celebrated attraction, but it is not necessarily the best starting point. Here is the optimal route recommended by those who know the area well, designed to make the most of your time, avoid the peak hours, and enjoy the best light at each site.

08:45 – Arrive at the Palatine Hill

The Palatine opens with the Roman Forum at 09:00, accessed from the Via Sacra entrance near the Arch of Titus. In the early morning the hill is almost deserted. The low-angle light illuminates the ruins of the imperial residences with extraordinary chromatic intensity, and the morning air is still cool. Dedicate approximately 60–75 minutes to the Palatine, visiting the Domus Augustana, the Palatine baths and the Farnese Gardens, from which there is a panoramic view over the entire Roman Forum.

10:15 – Descend to the Roman Forum

Descend to the Roman Forum via the internal pathway connecting the Palatine. At this time the forum is still relatively tranquil. Walk along the Via Sacra from east to west: Arch of Titus → Temple of Vesta → Temple of Julius Caesar → Basilica Julia → Temple of Saturn → Curia Julia → Arch of Septimius Severus. The complete route takes approximately 90 minutes if done at a relaxed pace, with attention to the explanatory panels.

12:00 – Walk Along the Via dei Fori Imperiali

Exit the Roman Forum on the Capitoline side and reach the Via dei Fori Imperiali. Walk it on foot from the Forum square towards Piazza Venezia: along the way you can observe the Forums of Nerva, Augustus (with internal access to the remains), Caesar, and the Forum of Trajan with Trajan's Column. This section on foot takes approximately 45–60 minutes, photography stops included.

13:00 – Lunch Break

There are many options for a break near the Forums and the Colosseum. Avoid the restaurants immediately adjacent to the monuments (high prices, mediocre quality) and move 5–10 minutes on foot towards the Celio or Testaccio neighbourhoods for excellent restaurants at reasonable prices. A break of 45–60 minutes is recommended, especially in summer.

14:00 – Markets of Trajan (Optional)

The Markets of Trajan — accessible with a separate admission to the Museum of the Imperial Forums — are a valuable addition for those wishing to deepen their understanding of the forums. This six-storey complex, built on the Quirinal slope at the beginning of the 2nd century AD, was a kind of shopping centre of antiquity. Today it houses a modern museum with artefacts from the Forums. Recommended duration: 60–75 minutes.

15:30 – The Colosseum in the Afternoon

Reach the Colosseum in the late afternoon. The queues at 15:30–16:00 are generally shorter than in the morning, and the afternoon light illuminates the interior of the arena with warm tones perfect for photography. Dedicate 90–120 minutes to the Flavian Amphitheatre, climbing to the second level for the view down onto the arena and enjoying the panorama of the Arch of Constantine at the exit.

Forums First or Colosseum First? The Expert Debate

It is one of the most frequently asked questions among visitors planning a trip to Rome: is it better to start with the Colosseum and then move to the Roman Forum, or to do the route in reverse? There is no universally correct answer, but there are solid arguments on both sides. Here is an honest analysis of the pros and cons of each sequence.

Option A: Colosseum First, Then the Roman Forum

Advantages: The Colosseum is the most iconic attraction and its visual impact on first sight is at its maximum. Starting with the most anticipated monument can be psychologically motivating. Moreover, if time is limited and there is a risk of not completing the full route, it is better to have already seen the Colosseum.

Disadvantages: The Colosseum is also the monument with the most visitors: arriving in the morning means encountering the day's peak crowds. After two hours in a busy environment, energy levels for exploring the Roman Forum with real attention may be depleted. Furthermore, morning light is not the best for photographing the interior of the Colosseum.

Option B: Palatine and Roman Forum First, Then the Colosseum

Advantages: The Palatine generally has fewer visitors in the early morning, allowing for a quieter experience. The Roman Forum visited mid-morning, when the light is already good but the crowds have not yet peaked, offers optimal conditions. The Colosseum in the late afternoon benefits from warmer light and slightly lower visitor numbers than in the morning. Finally, following this order means respecting the historical chronology: from the emperors' palaces (Palatine) to public life (Forum) to the politics of spectacle (Colosseum).

Disadvantages: There is a risk of "saving the best for last" and arriving at the Colosseum tired. For visitors with limited mobility or families with young children, this longer route can be physically demanding.

The Expert Recommendation

The vast majority of experienced Rome guides recommend Option B: Palatine → Roman Forum → Via dei Fori Imperiali → Colosseum. The chronological sequence helps build an organic understanding of ancient Rome, and concluding with the Colosseum — even with tired legs — guarantees a high emotional impact finale. The late afternoon light on the Colosseum is widely acknowledged as the most photogenic and theatrical of the day.

A practical note: whatever sequence you choose, plan your experience at least several days in advance, especially in high season. Guided experiences that cover both sites in a single tour are often the most efficient solution — an expert guide optimises the route according to the conditions of the day.

The Connection Between the Imperial Forums, the Colosseum and the Palatine Hill

The forum complex of Rome should never be thought of as a collection of separate, independent monuments. The Roman Forum, the Imperial Forums, the Palatine and the Colosseum form an organic urban system, designed — with variations and additions over the centuries — to represent the ideology and power of Rome. Understanding the connections between these places transforms a tourist visit into a genuine experience of historical comprehension.

The Palatine: The Root of Everything

The Palatine Hill is the legendary cradle of Rome: here Romulus traced the pomerium, the sacred boundary of the city, in the 8th century BC. Throughout the Republican period it was the residential quarter of the Roman aristocracy — living on the Palatine was a mark of status. With the advent of the Empire it became the exclusive residence of the emperors: Augustus lived here his entire life in a relatively modest house, but his successors progressively built an ever more grandiose palace complex that eventually occupied the entire hill. Descending from the Palatine to the Roman Forum is still today a physical gesture that reproduces the daily movement of the ancient Romans: from private residence to public life.

The Roman Forum: The Beating Heart

The Roman Forum was the place where the Palatine (private power) met the Capitoline (religious power) and expressed itself in the city's public life. The comitia (popular assemblies), the law courts, the temples, the shops, the public speeches: everything happened in the Forum. When Caesar, Augustus or Nero wanted to communicate something to the Roman citizens, they did so through the construction or modification of buildings in the Forum. Architecture was the primary instrument of political communication.

The Imperial Forums: The Projection of Power

While the Roman Forum remained the "democratic" heart of the city, the Imperial Forums represented the progressive personalisation of power. Each emperor built his own forum as a statement of personal prestige and dynastic ambition. The series of forums from Caesar to Trajan traces, in architectural terms, the transformation of Rome from a Republic to an autocratic empire: spaces become increasingly grandiose, temples increasingly magnificent, statues increasingly superhuman in scale.

The Colosseum: The Theatre of Power

The Colosseum completes the picture. Built by Vespasian (who had also built the Forum of Peace) on land previously occupied by Nero's private garden, the Amphitheatre was a political gesture as much as an architectural one: returning to the people a space that the mad emperor had appropriated for himself. The games held there — funded by the emperor, free for the people — were the most powerful instrument of social control in the Roman world. Understanding the Colosseum in the context of the forum system means understanding how ancient Rome worked as a society.

Frequently Asked Questions: Imperial Forums & Roman Forum

Clear, up-to-date answers to the most common questions from visitors planning to see the Imperial Forums and the Roman Forum in Rome.

How do I access the Imperial Forums and the Roman Forum?

The Roman Forum and the Palatine Hill are included in the same €18 combined admission as the Colosseum, valid for two consecutive days. The Roman Forum is entered from the Via Sacra gateway (near the Arch of Titus) or the Largo Romolo e Remo entrance. The Via dei Fori Imperiali is a public street that can be walked freely at any time to view the external remains of the imperial forums.

What is the difference between the Imperial Forums and the Roman Forum?

The Roman Forum is the original civic centre of ancient Rome, dating back to the 7th–6th century BC. It served as the political, religious and commercial hub of the city. The Imperial Forums are a series of monumental squares built between the 1st century BC and the 2nd century AD by successive emperors — Caesar, Augustus, Vespasian, Nerva and Trajan — as extensions designed to celebrate imperial prestige. In total the complex comprises six forums covering approximately 2.5 square kilometres of monumental public space.

How long does it take to visit the Imperial Forums and the Roman Forum?

For a thorough visit, allow at least 2–3 hours for the Roman Forum and the Palatine Hill alone. Adding the Imperial Forums along the Via dei Fori Imperiali, plan for 4–5 hours. If you include the Colosseum in the same day, you should schedule a full day of 7–8 hours. A guided tour with an expert significantly enhances the experience and makes efficient use of the time available.

Is it better to visit the Colosseum first or the Imperial Forums?

Expert guides consistently recommend visiting in this order: Palatine Hill → Roman Forum → Via dei Fori Imperiali → Colosseum. This sequence follows the chronological history of Rome and ensures you experience the Colosseum in the best light of the day (late afternoon). The Palatine in the early morning has the fewest visitors and the most photogenic conditions.

Which monuments in the Roman Forum are most important?

The highlights not to miss in the Roman Forum are: the Via Sacra, the Temple of Saturn, the Temple of Julius Caesar, the Arch of Septimius Severus, the Curia Julia (Roman Senate), the Temple of Vesta and House of the Vestals, and the Arch of Titus. The Palatine Hill adds the imperial palace ruins, the Farnese Gardens and magnificent views over the whole forum complex.

Can the Imperial Forums be visited at night?

The Via dei Fori Imperiali is a public street accessible freely at any hour, and the monuments are illuminated with striking artificial lighting in the evenings. Access to the interior of the Roman Forum and the Palatine Hill requires visiting within official opening hours. Some authorised operators organise dedicated evening experiences that allow access to parts of the site after standard hours, creating a particularly evocative atmosphere. These require advance arrangements.

Is there a guided tour that covers both the Roman Forum and the Colosseum?

Yes, there are combined experiences that cover the Colosseum, the Roman Forum and the Palatine Hill in a single guided tour. These typically last 4–5 hours and are particularly recommended for those who want to understand ancient Rome as a whole, not just as separate monuments. Check our Guided Tours page for a full comparison of available options.
