Atik Valide crowns a hill above Üsküdar as one of Mimar Sinan's largest and most complete works, a whole small town of stone. You climb to a wide colonnaded courtyard, its domes carried on slim columns around a fountain and a few old cypresses, one of the calmest squares in the district. Inside, the prayer hall opens under a broad dome, and the wall around the mihrab carries some of the finest İznik tile in the city: tomato red, cobalt and turquoise in panels of carnations and tulips.
Nurbanu Sultan commissioned the complex, and Sinan built it in his eighties. Around the mosque he set a madrasa, a soup kitchen, a caravanserai, a Quran school and a hospital that later became the city's asylum. Atik means old, the name the mosque earned once a newer valide mosque rose down by the shore. It is a working mosque and a quiet neighbourhood landmark both, drawing far fewer visitors than its size deserves, and the outer buildings now stand among ordinary houses and shops.
