The Senate of Curia Julia is the third Senate named Curia in the ancient Roman city. It was built by Julius Caesar in 44 B.C., but the work was interrupted by Caesar's assassination. The building was eventually completed by Caesar's grandnephew Octavian, the future emperor of Augustus, in 29 B.C. In A.D. 94, Curia Julia was rebuilt by Emperor Domitian in accordance with Caesar's original plan. The building was damaged by fire in 283 AD and repaired again. In 630 A.D., Pope Respect I transformed the Senate into St. Adriano Alfred Church. The building was further restored in the 1930s, removing various medieval appendages and restoring the original Roman architecture. Curia Julia is one of the few well-preserved Roman buildings. The building style of the Senate is not in harmony with the surrounding buildings. It is a bit like the modern warehouse, the square roof and the triangular roof. Despite its poor appearance, many important events in ancient Rome were decided here by consultation.
The Senate was the political center of ancient Rome, with a brown roof and mosaic of marble floors and exhibits. The relief and design floors were still visible. In the seventh century, the fire was transferred to the church and continued to be restored. They have been preserved to this day.
