This is the Sarahatun Mosque, built in 1465 in wood. An offcial site gives: "It was built as a mosque in 1465 by Sarahatun, the mother of the Akkoyunlu Ruler Hasan Bahadır Han. The mosque has a square plan and its pulpit is one of the beautiful examples of stone workmanship. Although the mosque, whose minaret was completed in 1898, was built as a social complex, today only the mosque part exists. It is still open to worship." I have not visited it in 2006 (closed, waiting for restoration), but in 2007 I was allowed in, to see the restoration in full swing. I hope to return someday to show the result.
