The mosque's western part has almost entirely disappeared over the years, but the rest of the structure (almost half of the original along the north-south axis) was recently restored. It includes, to the south, the sanctuary (comprised of a domed chamber, ten meters per side) with its iwan overlooking the court; the main portal iwan is found opposite it, on the north side of the court. In addition to the main portal, two lateral entrances were formerly located on the east and west. Of the two, only the eastern portal exists today. The design accentuates the space of the domed chamber by raising its dome higher than the level of the other two iwans on the site. This impression of size is most prominent when one passes from the low vault of the iwan to the lofty space of the domed chamber, where the mihrab is situated on the south qibla wall.
