This is within the Roman bath house, and displays artifacts found during local excavations, including ornate sarcophagi. One of these (not always on display) is 3rd century and has an intricate depiction of a crank-driven sawmill, the first known example.

This naturally hot swimming pool would feel like Disney if only it was clean - you'll wonder where's the crazy-golf and the popcorn cart? Supposedly founded by Cleopatra, it was part of an ugly rash of hotels built from the 1980s, so being 2000 years old she'd be wizened beyond hope of any spa cure. The hotels were later cleared away leaving only this pool, with fluted column pieces sunk within it for extra authenticity. The shop sells bathing suits and towels, and there are lockers.
