On the courtyard of the Eyüp Mosque a wall opposite the mosque, mostly covered with many tiles from different periods and quality hides the tomb of Eyüb from sight. It is an octagonal building, three sides of which project into a vestibule, where the many visitors gather and pray. There the walls are again covered with (often best) Iznik tiles. I put the pictures of the outside wall into a sub-gallery, there simply are too many.
