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 in 1617 aged only 27; his türbe was constructed between 1617 and 1619 and like the mosque, features fine İznik tiles.
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 order of Murat).
