Pictures taken at the mevlevi cenotaphs mosque. In the 13th century under Sultan Veled the Mevlevi Order became widespread in the 15th century and especially in the 16th century during Sultan Divani, and his Dervish Lodge (dergah) became the second biggest dervish center in the world, after Konya. It was initially built of wood, burned down and then was restored several times. In 1844 a minbar and minaret were added. After a fire in 1902 the dergah was given the present form under Abdulhamid II in 1908. There is a big domed semahane (where the sema, the whirling dance ceremony, was performed). At its side there are the tombs of several dervishes. Outside there are kitchens, a fountain and cells for the dervishes.
