The Historical Bath of Siba — Hamam Sibah (Persian: حمام سیبه), is a historical bathing complex of the ancient Sassanid culture, located in present-day southern Iran near the Straits of Hormuz.
The Historical Bath of Siba bath structures and ruins are located in the Kukherd District (Persian: بخش كوخرد), in Hormozgan Province. They are under the administration of the city of Bastak.
The ancient baths are an archaeological site of Sassanid architecture. Modern public baths nearby use the same reportedly healing waters.
The Historical Bath of Siba public baths were built at natural hot springs, during the Sassanid Empire era (224– 651 CE). Ancient Sassanians built public baths to serve as rest centers. The baths served Sassanid government officials, the merchants from nearby sea ports and desert caravan routes, and the public.
Some of the baths had practitioners who offered healing treatments, using medicinal herbs and essential oils. These ointments were generally used for relieving joint pain and treating skin diseases.
The baths were known as the 'dumb doctor' because healers also treated patients silently with its healing hot spring waters.
