Arch of Augustus

The Arch of Augustus is an Ancient Roman arch constructed in the city of Susa, Piedmont, in the province of Turin [1]. It was built in 9–8 BC to record the renewed alliance between Emperor Augustus and Marcus Julius Cottius, a Celto-Ligurian ruler who had been made king and Roman prefect of the Cottian Alps [1]. From above, the arch forms a rectangle 11.93 metres long and 7.3 metres wide [1]. It rests on two large bases and there is only one archway [1]. The entablature rests on four Corinthian columns placed at the extremities of each corner, such that a quarter of each drum is embedded in the monument [1].
