Basilica Sempronia
Rome, Italy
The Basilica Sempronia was a structure in the Roman Forum during the Republican period. It was one of four basilicas to make up the original Roman Forum alongside the Basilica Porcia, Basilica Aemilia, and Basilica Opimia, and was the third built. Although excavations have revealed remains of the basilica as well as the structures that originally stood in its place, none of them are visible from the Roman Forum.
