The Grand Bath overlooked the Xanthos valley to the southeast of the stadion. Double doors connect its three rooms. Windows under 7 arches gave the bath a local alternative name, “Yedi kapı” (Seven gates) and must have provided a splendid effect. The Wikipedia suggests this room could be the "exedra in the baths" donated by Opramoas to Tlos and would date the baths to 100-150 CE. The cold section was in the east, the warm section to its west has been converted into a church in the 12th century. Further west was the hot room, which was converted into a narthex to that church.
