The city of Augusta, which has a population of about 34 000, can be easily identified standing on Isolotto di Augusta. The city is connected to the mainland N of it by two bridges, under which boats can pass from Porto Xifonio to Porto Megarese. Close S of these bridges stands the old citadel. The cathedral has an elevation of 51 m near the N end of the city, but owing to the high buildings surrounding it, it is not visible from sea.
