The adjacent höyük (tumulus) was excavated by Prof. Dr. Remzi Oğuz Arık in 1937 revealing the Phrygian and Roman remains.
Prof. Dr. Arık was able to date construction of the baths to the reign Caracalla by coins found during the excavations supported by contemporary inscriptions, whilst further coins indicated the baths were in continuous use for about 500 years, undergoing repair from time to time [REF].
