Also: Imperial hall, Marmorsaal

Modern German term to designate the large and richly decorated halls often found in large thermae, especially in the bath-gymnasia of Asia Minor. It was often connected to the palaestra and had one or more exedrae. The function may have been associated with the Imperial cult. The abundant use of marbles inspired the alternative term ‘Marmorsaal’ (marble hall).
