Inside are Sultan Baba's wooden cenotaph and a patent of 1787, from the reign of Selim III. He was a member of the Şemsi branch of the Halveti order. In the burial ground to the right of the tomb entrance is an Ottoman grave dated 1879. Go to Değirmendere from the city centre and take the local buses from there.
