Of the lower town by the harbour, which had buildings of some importance of the imperial period (amphitheatre, baths, etc.), little is now visible, and its site is mainly occupied by a new quarter built by Pope Pius VI. Of the ancient harbour constructed by Antoninus Pius insignificant remains exist, and it is largely silted up. Close to it is the small modern port. Near the amphitheatre was found in 1838 the famous marble bust of Sophocles, now in the Lateran Museum, Rome.
