ABSTRACT
The Arch of Augustus in Rimini is the oldest Roman arch that has survived until today. The arch of Rimini is the oldest Roman arch to have survived so far, and almost certainly was topped by bronze statues. The arch from the beginning was part of the Roman walls of the city, and was initially flanked by two square towers, whose bases were identified during modern excavations. To consolidate the inner masonry of the arch abutments, a preliminary and temporary repointing of the surface was made, so avoiding any leakage of successive groutings. The final photographic survey of the arch provides the exact measures and deformations of the monument. In the case of the Arch of Augustus in Rimini the knowledge of the real components of the wall in all its thickness gave the opportunity to make a structural modeling adhering to reality in a much greater degree than usual.
