In Catania, Sicily, there’s a wonderful ancient church that was built from the ruins of a 1st or 2nd century Roman bath complex (see above). It’s known as the Chiesa della Rotonda for its huge central domed area, which perhaps was the caldarium or hot room of the baths. This is a picture of the interior arches of the rotunda, which still have some medieval and baroque period frescoes adhering to the walls.
