History+
Construction of this complex began in 54 BC. For its realization, residential buildings in the Subura district had to be demolished, parts of the Capitoline Hill removed, and the Senate's Curia relocated. Funding was provided by the spoils of war from the Gallic War. A central element of the complex was the Temple of Venus Genetrix, vowed by Caesar before the Battle of Pharsalus and dedicated in 46 BC along with the entire Forum.
