The Roman Baths of Ankara have all the typical features of a classical Roman bath complex: a ''frigidarium'' (cold room), a ''tepidarium'' (warm room) and a ''caldarium'' (hot room). The baths were built during the reign of the Roman emperor Caracalla in the early 3rd century to honor Asclepios, the God of Medicine. Today, only the basement and first floors remain. It is situated in the Ulus quarter.
