The Caracalla Nympheum was built in honor of, and dedicated to, Emperor Caracalla (r. 211-217 AD) on the occasion of his visit to Laodicea. It underwent four repair phases, the last in the early 5th century. It had two storeys in Corinthean order. It had an almost square rectangular (8,90 x 7,90 meters) pool with two apsidial pools on either side. The parapet balusters extant are decorated with scenes of Heracles, Abduction of Ganymede and Theseus slaying the Minotaurus.
