The building is made of bricks and consists of a square hall with walls which are 11,45 meters high, a massive round drum and a conical roof with an inner dome hidden under it. The dome is connected to the square walls it rests upon by an octagonal belt. The structure between the dome and the octagon is decorated with 16 shallow niches. Their form is not lancet-like as those commonly found in the Islamic architecture of Central Asia, but rather semicircular. This is a motif that can be found in the marble 8th-century mihrab at the Baghdad Museum, and has seldom been used in Central Asia: another comparable case that can be found in Turkmenistan is that of the mihrab of Muhammad Ibn Zayd's 11th-century mosque, from Merv. However, the two are located too far away to be considered prototypes.
