The Roman Bath, one of the largest structures in the city of Hierapolis, has been serving as the Hierapolis Archeology Museum since 1984. In addition to the artifacts from the Hierapolis excavations, there are also artifacts from the Lycos (Çürüksu) valley cities such as Laodikeia, Colossai, Tripolis and Attuda. In addition, the archaeological finds obtained from Beycesultan Mound, which gives the most beautiful examples of the Bronze Age, constitute an important part of the museum. In addition, artifacts unearthed from some settlements in Caria, Pisidia and Lydia are collected and exhibited in the Hierapolis Museum.

Three indoor spaces, which are parts of the Hierapolis Bath, and the library and gymnasium adjacent to the east are arranged as museum display areas. The museum, where many small and large works are exhibited, consists of three indoor spaces. The works exhibited in the open area are mostly marble and stone works.
