Ankara’s most revered mosque is Hacı Bayram Camii, near the Temple of Augustus & Rome. Hacı Bayram Veli was a Muslim ‘saint’ who founded the Bayramiye dervish order around 1400. Ankara was the order’s centre, and Hacı Bayram Veli is still revered by pious Muslims. The mosque precincts are ringed with shops selling religious paraphernalia  (including wooden toothbrushes as used, supposedly, by the Prophet Mohammed). You can buy food to feed the pigeons in the nearby pigeon feeding area (Güvercin Yemleme Alanı).
