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 27.7 m × 21.5 m (91 ft × 71 ft) for the eastern one and 21.7 m × 15.7 m (71 ft × 52 ft) 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 that Dušan Magdolen proposed that Lepsius XXV is a mastaba.

A further peculiarity of the structure is the lack of associated mortuary temple.
Instead, the eastern tomb boasts a small offering chapel built of undecorated white limestone and situated within the tomb superstructure.
Its ceiling reached 5 m (16 ft) high.
Excavations revealed small pieces of papyrus inscribed with a list of offerings as well as fragments of an alabaster statue of a woman clothed in a simple robe.
The burial chamber revealed scant remains of the female owner and a few pieces of funerary equipment.

The western tomb was built subsequently to the eastern one and seems to have served to bury another woman.
Builders graffiti uncovered during the Czech excavations demonstrate in all likelihood that the monument was built under Nyuserre, its owners possibly amongst the last members of the broader royal family to be buried in Abusir, the necropolis being abandoned by Nyuserre's successor Menkauhor.
