We spent one day doing Sufi things. The Sufi's have a long and interesting history. This is from a cemetary at what is usually called the "Sufi Museum."
Actually, however, the museum is dedicated to the sect of sufis that is associated with whirling dervishes. In Turkey, the sect is known as the Mevlevi order.
The museum is a museum because it was once a Mevlevi lodge, probably similar to a church, and Ataturk dissolved the orders, prohibited the use of mystical names and titles and costumes pertaining to their titles, impounded their assets, and banned their ceremonies and meetings. This was part of Ataturk's attempt to pry state and religion apart.
