Senâm

Senâm is the name of a long, low hill situated in M'sila Province, Algeria, southwest of Algiers. The hill is covered with a large number of stone circles.
These stone circles are built of natural limestone, with standing slabs high. The diameter of the circles varies between about and. The entrance to the circles is on the southeastern side of the hill, through a larger, surrounding circle. It is uncertain if the niche was once roofed. The center of the circle is filled with stones for unknown purposes, possibly as a grave.
