In 1543 he built the Şehzade Mosque for Suleiman's son Mehmed, dead at twenty-two, his first masterpiece. His most famous work is the Süleymaniye, and he also designed the Sulaymaniyya Takiyya in Damascus, introducing the Ottoman style.
In the Selimiye Mosque at Edirne, his masterpiece, he set an octagonal dome 31.28 metres wide on eight piers and claimed it surpassed Hagia Sophia. He died in 1588 and lies in a tomb of his own design.
