The Tash Han (Stone Han) is a nice building with inside still the the activities of a proper han: trade, a tea house, and a fountain with two lions that have worn down to almost nothing.
The photos of Sivas are truly great. One thing is missing though: the tomb of a great Saint of Christendom, St. Blasius (Blaise) of Sebaste (modern Sivas). His tomb should be near the ruins of a citadel on a hillock in Sivas (although the Sivas itself is at 1280m above sea level). Congratulations for the photos! You may know the place where St. Blasius' tomb is?
