Sokollu Mehmet Pasha Mosque sets four fragments of the Kaaba's Black Stone into its fabric — over the door, in the mihrab, on the minbar, and beneath the minbar's cone. Mimar Sinan built it in the early 1570s for İsmihan Sultan, daughter of Sultan Selim II, and her husband, the grand vizier whose name it carries. The site is a steep Kadırga hillside, so Sinan terraced the whole complex into the slope: you enter from the street below and climb a stair that passes beneath the medrese's lecture hall, surfacing in a courtyard ringed by student cells, the prayer hall facing you. Inside, a single dome rests on six supports, leaving the floor open and calm.
The İznik tiles belong to the workshops' finest decade, when a thick tomato red first held its colour under the glaze. They climb the mihrab wall and spread into the pendentives — turquoise, cobalt and that red woven into carnations and tulips. Light falls through coloured glass onto the painted dome. Today it remains a working neighbourhood mosque, little visited, its shaded courtyard one of the quietest corners of the old city to sit with Sinan's tilework.
