Rome has many squares. The Royal Square consists of a series of squares, which were built from 42 BC to 112 A.D. by Tulazhen, Augustus, Caesar, Nerva and Vespatian. In 1933, Mussolini attempted to build the Royal Square Street between the Colosseum and Venice Square, and most of the Royal Square was buried underground. Fori di Traiano is the largest square unearthed in the Royal Square. Except for some of the Tulazhen cylinders, the vast area of the 2nd century A.D. is almost empty. The Tulazhen cylinder was built to commemorate the defeat of the Dacian (from today's Romania) by Tulazhen. It has spiral reliefs depicting battles with the Dacian army. The original gold statue of Tulazhen at the top of the cylinder was lost in the Middle Ages, and now it is the statue of St. Peter.
