TheSouthern MazghunaPyramid is anancient Egyptian royal tomb which was built during the12th or the13th Dynasty inMazghuna, 5 km south ofDahshur,Egypt. The building was never finished, and is still unknown whichpharaoh was the owner, since no appropriate inscription have been found.
The pyramid was rediscovered in 1910 byErnest Mackay and excavated in the following year byFlinders Petrie.[1]

The pyramid can be dated to either late 12th Dynasty or early 13th Dynasty.
The pyramid might date to the 12th Dynasty, as the building shares some structural similarities to theHawara pyramid ofAmenemhat III. For this reason it is usually attributed toAmenemhat IV, while thenorthern Mazghuna pyramid is attributed toSobekneferu.
William C. Hayes (1953) believed that the southern pyramid was built during the 13th Dynasty, on the basis of some similarities with thepyramid of Khendjer.[2] In this case, it could have belonged to one of the many pharaohs who ruled in the 13th Dynasty.
The pyramid has a side length of 52.5 m (172 ft). The core masonry consists ofmudbricks and only reaches a height of one to two layers. Casing stones were not found; therefore, it is impossible to determine information about the planned inclination angle and total height.

The entrance of the pyramid is located in the middle of the south side. A staircase leads down to a short horizontal passage. Here is a wall niche, from where a blocking stone had been pushed into the passage. Another staircase leads to a second block, which, however, is still in its niche.
Finally a U-shaped chamber system leads to the burial chamber, which is topped by agable roof. There was an empty – but used –quartzitesarcophagus and some fewgrave goods (three limestone lamps, analabaster duck-shaped vessel, a make-up vessel made from the same material and a piece of polishedsoapstone) were found in it.
The complex is surrounded by a wavy wall, which incorporate the remains of the chapel in the middle of the east side; it consists of a large central chamber with two chambers on each side of the storehouse. The central chamber was attached in its southwestern corner with a sacrificial hall with a vaulted roof.
