The mosque was designed by the famous Ottoman architect Mimar Sinan and completed in 1566, during the years the Ottomans had control of the city. The mosque derives its name from the phrase Banya Bashi, which means many baths. (In the Turkish language Banyo means bath and Baş pronounced Bash means ‘head’ or ‘main’, so looking at the location it is built on, a more logical translation of the name would be ‘Head of the bath mosque’) The most outstanding feature of the mosque is that it was actually built over natural thermal spas; one can even see the steam rising from vents in the ground near the mosque walls. The mosque is famous for its large dome, diameter 15m, and the minaret.
