Once covered by a layer of limestone, the Pyramid of El Lahun (known as the Pyramid of Senusert II) was the first large mud-brick pyramid. Its limestone layer was removed during the Nineteenth Dynasty, by Ramses II, who used the pyramid as a quarry to build his temples. The pyramid is unique in that its core was a knoll of the bed-rock, on which the mud-brick pyramid itself was built, similar to the pyramid of Hawara, and then all cased with limestone. The pyramid measures 48 m in height with a base measuring 106 m in each side. Usually, the entrance of the pyramid is not located in its northern face. Instead, its architect had a way of hiding the corridor that leads into the burial chamber: that was by digging two wells perpendicularly outside the main building of the pyramid, to the south of it. These two wells are linked one to the other. The bigger well was used to lower the king’s sarcophagus to the depth of 12 m. Then, after passing through some corridors, one can reach the burial chamber, inside which was found a pink granite magnificent sarcophagus as well as an alabaster offering table. Next to the burial chamber is a room in which a golden cobra– probably once adorned a royal crown– was discovered. To the east of the pyramid was found the simply-designed mortuary temple surrounded by a limestone enclosure wall. To the north of the pyramid are 8 rock-cut tombs side by side to the remains of a queen’s pyramid.
