The Seyitgazi Complex as seen from the East.
On the left of the picture: the dome and the minaret of the mosque, and the high dome of the Türbe (mausoleum) of Seyit Battal Gazi. On the right: some buildings belonging to the ‘Tekke’ of the Bektaşi Order.
What we see dates from the period 1465-1511 and is a good example of the imperial Ottoman style.

Tekke or Dergah = the largest kind of building (often a complex) designed specifically for gatherings of a Sufi brotherhood. It was a place for spiritual retreat and character reformation, and often served as hospices for Sufi travelers and Islamic students.
