This was once a public bath. The outer walls are crumbling, but they once separated the different baths (cold/hot/tepid). The long pipe carried water into the cavern. I wondered what the squares were for. Likely they are the base for what was once a pillar or support under the floor. But I decided I liked to think of them as little stools for each person wanting a bath...kind of like those little seats in a hotel hot tub. Right.This section was for the warm water. The modern Turkish hamams (public bath houses) are based on the ancient Roman ones. They said men bathed up until noon. Women bathed after that. I wonder if Paul took a bath here.
