The Hamamni Persian Baths is located in a historical building of Stone Town, Zanzibar. The name Hamamni is also used to refer to the neighbourhood where the building is located.
The Baths were built between 1870 and 1888 for sultan Barghash bin Said for use as public baths, and maintained this function until 1920. They are referred to as "Persian" because their construction was commissioned to Shirazi architects. The word "Hamamni" means "the place of the baths".
The building had a complex structure with several rooms, including hot and cold baths, toilets, shaving areas, and a restaurant. Hot water was provided by underground aqueducts.
