The Tabularium was the official records office of ancient Rome and housed the offices of many city officials. Situated within the Roman Forum, it was on the front slope of the Capitoline Hill, below the Temple of Jupiter Optimus Maximus, to the southeast of the Arx and Tarpeian Rock.
Within the building were the remains of the temple of Veiovis. In front of it were the Temples of Vespasian and Concord, as well as the Rostra and the rest of the forum. Presently the Tabularium is only accessible from within the Capitoline Museum, although it still provides a panoramic view over the Forum.
The construction of the Tabularium was ordered around 78 BC by the dictator Lucius Cornelius Sulla. The building was completed by Quintus Lutatius Catulus, consul in 78 BC. This was part of a public works programme for the redevelopment of the Capitoline Hill, which had been damaged by a fire in 83 BC. The construction by Catulus is not mentioned in the ancient literature. It is known through an inscription.
