The türbe (tomb) of Sultan Ahmet I, the Blue Mosque’s great patron, is on the north side of the mosque facing Sultanahmet Park. Ahmet, who had ascended to the imperial throne aged 13, died one year after the mosque was constructed, aged only 27. Buried with Ahmet are his wife, Kösem, who was strangled to death in the Topkapı Harem, and his sons, Sultan Osman II (r 1618–22), Sultan Murat IV (r 1623–40) and Prince Beyazıt (murdered by Murat). Like the mosque, the türbe features fine İznik tiles.
