Located in central Rome, the Forum of Augustus was built by Augustus and inaugurated in 2 BC.
“The Forum Augustum or Augusti was the second of the imperial fora, adjoining the Forum Iulium, built by Augustus to provide additional room for the courts, and for other needs of the increasing population. The site was purchased by Augustus from its owners with the proceeds of the spoils of war, but he did not succeed in acquiring enough land to carry out his original plan. Within the forum was the temple of Mars Ultor which formed the essential element of the forum as the temple of Venus Genetrix did that of the forum Iulium. The work was greatly delayed, but that on the forum was hurried at last and this was opened before the temple was finished, although its actual dedication is said to have taken place on 1st August, 2 B.C., at the same time as that of the temple. Because of the temple of Mars, this forum was sometimes called forum Martis.” (Citation: http://www.creatinghistory.com/the-forum-of-augustus/ )
