The Forum of Caesar, also known by the Latin Forum Iulium or Forum Julium, Forum Caesaris, was a forum built by Julius Caesar near the Forum Romanum in Rome in 46 BC.
The need to renew the oldest administrative and judicial structures and to adapt them to the new magnitude, both physical and political, of the city of Rome was the pretext that Julius Caesar used to complete a brilliant and innovative project of self-glorification. Thus, in direct competition with his rival Gnaeus Pompeius (also known as Pompey the Great) who in 55 B.C. had inaugurated his splendid theatre in Campus Martius, the following year Caesar appointed a group of his closest supporters to design a new, monumental complex. He justified its construction with the need to expand the Roman Forum.
