Time Out says
The Süleymaniye Hamamı was built by Mimar Sinan between 1550-1557 under the orders of Sultan Süleyman the Magnificent. It was constructed along with the Süleymaniye social complex (including educational establishments, a medical college, and a public soup kitchen). The three-part hamam is mixed and admits families and couples only. The private seating area once reserved for Sultan Süleyman himself to bathe is one of the sections of the hamam still in use.
