English: Founded by Mustafa III, built 1759-1763, design by Mehmet Tahir Aga, "greatest and most original of the Turkish baroque architects" (I quote Strolling through Istanbul). It's built on a raised platform, and stands aloof from the busy Ordu Caddesi. This is the entrance to a flight of stairs, from that Caddesi, to the right we see a sebil, to the left is the mausoleum of sultans Mustafa III and Selim III.
