Karl Richard Lepsius, who visited Egypt in 1843 provided a first brief description and catalogued it as number XXIX (29) in his pyramid list. Gaston Maspero entered the underground chambers in 1881. A first, very brief, and unsystematic excavation of the ruins was made in 1930 by Cecil M. Firth. Then the ruins were once again covered with sand.&lt;br&gt;
