The Forum is confusing on the ground because it is not one place. It is a thousand years of city centre stacked on the same few acres, from the eighth century BC to the seventh century AD, with each layer demolishing or building over the last — and then a further thousand years of people taking the stone away. Knowing which of those you are standing in front of is most of the battle.
It began as a swamp with graves in it
The valley between the Palatine and the Capitoline was low, wet, and prone to flooding from the Tiber. Nobody lived in it. The hills around it did, and they used the basin below as a burial ground — Iron Age graves from the tenth and ninth centuries BC have been excavated along what later became the Via Sacra.
What turned a marsh into a plaza was drainage. In the late seventh or early sixth century BC the Cloaca Maxima was cut through it, one of the earliest sewers anywhere, traditionally attributed to the Etruscan king Tarquinius Priscus. The Forum exists because someone drained it.
Rome's own account — that the valley became neutral ground after Romulus made peace with the Sabines — comes from Livy, Dionysius of Halicarnassus and Plutarch, all writing centuries later and all mixing history with foundation myth. The research rates that tradition medium confidence. The drainage and the graves are archaeology; the handshake is a story Rome told about itself.
It was never planned
The single most useful thing to know here is that nobody designed this.
The Forum accumulated. Buildings went up, burned down, were rebuilt at a different angle, were demolished to make room, or were repurposed into something else entirely. It was famously congested and chaotic until Caesar began imposing order on it. Looking for a coherent civic plan is looking for something that was never there.
That is also why the ground level rises as you walk: you are walking across centuries, not across a floor.
The games were here first
Before the Colosseum opened in 80 AD, the main square of the Forum was where gladiatorial combat happened in Rome. Temporary wooden stands were put up around the open space and taken down again.
Cicero is among those describing it. The Colosseum did not introduce the games to Rome; it moved them out of the middle of the city and gave them a permanent building.
Three things in the Forum most people walk past
- The Vicus Jugarius, the street running past the Basilica Julia. Some historians think it is older than the city — a trade route down to the Tiber that existed before there was a Rome to formalise it.
- The Shrine of Juturna, a spring dedicated to a water nymph, where Romans came for water they believed healed. The legend attached to it says Castor and Pollux watered their horses here after the battle of Lake Regillus.
- The Imperial Ramp, discovered and restored in 2015: a covered passage letting Domitian come down from his palace on the Palatine directly into the Forum without appearing in public. An emperor's private staircase into the centre of Roman life.
What Giacomo Boni found under the paving
In 1899 the archaeologist Giacomo Boni lifted the black paving stones known as the Lapis Niger and found an archaic altar and an inscribed stele beneath them. It rewrote what was understood about Rome's regal period.
Three years later, in 1902, he found the archaic necropolis along the Via Sacra — the ninth- and eighth-century BC graves that proved the valley had been in use long before the city urbanised.
The 2020 tomb, and what it wasn't
In 2020 archaeologists working near the Curia Julia and the Lapis Niger found a sixth-century BC underground chamber holding a tufa sarcophagus about 55 inches long, and a circular altar.
It was reported worldwide as the tomb of Romulus. The sarcophagus was empty, and scholars do not think it ever held anyone. The reading that fits the evidence is a heroon — a shrine to a mythical founder, built for worship rather than for burial. Which is still remarkable, and is a different claim.
Where the marble went
The Forum did not simply fall down.
Fires did real damage — 210 BC, 9 BC, the fire of 64 AD under Nero, 191 AD under Commodus, 283 AD under Carinus. An earthquake in 847 AD collapsed a great deal, burying the church of Santa Maria Antiqua, which is partly why it survived.
But the missing marble was taken, deliberately and at scale. Through the Middle Ages and the Renaissance the Forum was a quarry: popes and noble families carried the stone off for new palaces and churches, St Peter's among them, and burned much of the rest into lime for mortar. A substantial part of the Roman Forum left the site as cement.
Modern conservation has taken the opposite view. The policy is stabilisation, not reconstruction — water damage prevented, marble protected from pollution, and anastylosis, the re-erecting of fallen columns, used sparingly. The three columns standing at the Temple of Vesta were put back up in the 1930s.
Four things almost everyone believes that aren't true
| Claim | Verdict | What is actually the case |
|---|---|---|
| It was built as a planned civic centre | False | It grew for a thousand years, with constant demolition and reuse, and was chaotic until Caesar |
| The 2020 discovery is Romulus's tomb | False | The sarcophagus was empty; it is read as a shrine to the founder, not a grave |
| Gladiator fights happened at the Colosseum, not here | False | Before 80 AD the Forum's main square was the primary venue, with temporary wooden stands |
| The marble is all still here, just fallen | False | Most was carried off for other buildings or burned into lime |
