The mosque is the Ayazma Mosque, built 1760 by Sultan Mustafa III and dedicated to his mother. It is in a baroque style, and has some great ornaments that I did not hesitate to take pictures of. Also, it has several "houses" on its walls, meant for pigeons.
On the picture: The calligraphic inscription above the northern entrance to the complex. Late-Ottoman, from 1760. Behind this gatehouse lie the mosque’s gardens, which house numerous graves.
