was a smaller one for the Ka of the king. Pyramid Lepsius XXIV South of the pyramid of his mother Khentkaus II, Nyuserre built a pyramid for a queen, either a consort of himself or of his brother Neferefre. The pyramid is known today as Lepsius XXIV, after its number in Karl Richard Lepsius' pioneering list of pyramids. It originally reached about high with a base of , its core made of limestone and clay mortar organised in horizontal and accretion layers. Today the pyramid is heavily ruined, its outer casing of fine white limestone long gone, and it stands only tall. While graffiti left by the builders indicate that the construction of this pyramid dates to the later part of Nyuserre's reign and took place under the direction of vizier Ptahshepses, the name of the queen for whom the pyramid was intended is lost. Reptynub has been cited as a likely candidate. In the burial chamber, which is reached via a straight north–south passageway, the broken up mummy of a young woman was discovered. She stood around tall and died between 21 and 23 years of age. It is unclear whether the mummy is that of the original owner of the pyramid or dates to a later period as the mummification method employed could suggest. Excavations of the burial chamber yielded fragments of a pink granite sarcophagus as well as pieces of large calcite canopic jars and smaller funerary equipment. On the eastern side of the pyramid, the ruins of a small satellite pyramid as well as of a mortuary temple have been discovered. Both were heavily affected by stone robbing, which started as early as the New Kingdom and reached a climax during the Saite (664–525 BCE) and Persian (525–402 BCE) periods, making a modern reconstruction of the temple layout impossible. Lepsius XXV The ruins known today as Lepsius XXV constitute not one but two large adjacent tombs built as a single monument on the south-eastern edge of the Abusir necropolis. The peculiar construction, which Verner has called a "double pyramid", was known to ancient Egyptians as "The Two are Vigilant". The pyramids, both truncated, had rectangular bases of for the eastern one and for the western one, their walls reaching an inclination of about 78 degrees. This means that the construction resembled a pair of mastabas more than a couple of pyramids, in fact so much so
