The monument does not provide much information about its history since it is half-buried in the ground, and almost all its surfaces, both inside and outside, are covered with plaster; the anteroom and the bell-tower (formerly a minaret) are later additions. It is a rectangular building with sloped roofs on the north and south part, and an octagonal dome supported on a rectangular base. The initial wall masonry is discernible only on the east side. The monument is dated to the 9th century A.D.
