This mosque with its single focal dome, four smaller domes and just one minaret pales in comparison with Istanbul’s other grandiose mosques, but beauty is not something the Rustem Pasha Mosque is short of. The 2300-plus intricately designed 16th-century Iznik tiles decorating the inside have a floral and geometric theme that complements the Ottoman architecture and massive glass chandeliers cascade gracefully from the mosque’s ceilings.
