Şehzade Mosque sits on a low rise between the aqueduct and the bazaar quarter, and its plan is what makes it worth the stop. A central dome rests on four equal half-domes of matching span. Step inside and the space feels open and evenly lit, with no front and no back, the semi-domes pulling your eye upward in every direction at once. The two minarets are unusually ornate for him, carved with bands of geometric relief he mostly avoided later.
Suleiman the Magnificent ordered the mosque after his son Şehzade Mehmed died of smallpox in 1543, at twenty-two, the heir everyone expected to take the throne. In the garden behind stands Mehmed's tomb, its dome fluted like a melon rind and its interior lined with tilework a generation older than Istanbul's famous İznik panels. Most visitors keep to the prayer hall and miss it. The mosque still serves daily prayer, while its courtyard draws people who come mainly for Sinan.
