Around the edge of the courtyard facing the turbe are the cells that were used by the resident dervish, these have been nicely restored into a small museum, some show how the rooms would have been arranged for various purposes - others hold significant artefacts. There are a few beautiful textile pieces, however the 'Serpush' that belonged to Shems of Tabriz (Mevlana's spiritual guide) amazed me - from the 13 century - yep so that is 800 years old.... or near about, it is 2 sided, and it says on the museum label that it is a 'fabric upon two sided carpet cap'. It has real substance and is similar to a mitre in style. I love the stitching. Amazing condition.
