Its exterior has a fortified appearance and the entrance is marked by a monumental portal with rich stone-carved decoration including a vaulted canopy of muqarnas. This entrance leads to a large interior courtyard surrounded by arcades, at the middle of which is a small square stone chamber elevated on four pillars, which served as a small mosque. Opposite the entrance, at the other end of the courtyard, is another portal which leads to the "winter hall": a main vaulted nave with a central dome (marked by a conical roof on the outside), from which other vaulted chambers open on either side.[1][2][3] The building also contains notable examples of Seljuk stone-carved animal motifs, including drain spouts resembling lion heads and serpentine dragon motifs along the lower arches of the elevated mosque in the courtyard.[2][4]
