The registered historical building, Şengül Turkish Bath located at the front side of Celal Efendi Prayer Room (Şengül Mosque) is from 16th century.
The famous traveler, scientist, author and folklorist from Kütahya Evliya Çelebi listed this Turkish bath among the others in his visit to Kütahya. After the restoration, the historical place was put into service in order to promote underground assets and exhibit them on a local and national scale in 2008.
