The Basilica Julia () was a structure that once stood in the Roman Forum. It was a large, ornate, public building used for meetings and other official business during the Roman Empire. Its ruins have been excavated. What is left from its classical period are mostly foundations, floors, a small back corner wall with a few arches that are part of both the original building and later imperial reconstructions and a single column from its first building phase. The Basilica Julia was built on the site of the earlier Basilica Sempronia (170 BC) along the south side of the Forum, opposite the Basilica Aemilia. It was initially dedicated in 46 BC by Julius Caesar, with building costs paid from the spoils of the Gallic War, and was completed by Augustus, who named the building after his adoptive father. The ruins which have been excavated date to a reconstruction of the Basilica by the Emperor Diocletian, after a fire in 283 AD destroyed the earlier structure. History and use Ancient Rome The first iteration of the Basilica Julia was begun around 54 BC by Julius Caesar, though it was left to his heir Augustus to complete the construction and name it in honor of his adoptive father. The basilica was built over the remains of two important Republican structures: the Basilica Sempronia, which was demolished by Caesar to make way for the new basilica, and pre-dating both, the house of Scipio Africanus, Rome's legendary general. The Basilica Sempronia was built in 169 BC by Tiberius Sempronius Gracchus and required the demolition of the house of Africanus and a number of shops to make room. The first Basilica Julia burned in 9 AD, shortly after completion, but it was reconstructed, enlarged, and rededicated to Augustus' adoptive sons Gaius and Lucius in 12 AD. The Basilica was restored after a fire in 199 AD by Septimius Severus, and later reconstructed by the Emperor Diocletian after another fire in 283 AD. The Basilica is bordered on its short sides by two important ancient roads which led from the Tiber to the Forum: the Vicus Jugarius to the west, and the Vicus Tuscus to the east. The ground floor was divided into five east–west aisles inside, with the central aisle forming a large hall that measured 82x18 meters, sheltered by a three-story high roof. The adjoining aisles to the north and south of the central
