Passage: Userkaf's pyramid is part of a larger mortuary complex comprising a mortuary temple, an offering chapel and a cult pyramid as well as separate pyramid and mortuary temple for Userkaf's wife, queen Neferhetepes. Userkaf's mortuary temple and cult pyramid are today completely ruined and difficult to recognize. The pyramid of the queen is no more than a mound of rubble, with its funerary chamber exposed by stone robbers.The complex is markedly different from those built during the 4th Dynasty (c. 2613–2494 BC) in its size, architecture and location, being at Saqqara rather than Gizah. As such, Userkaf's pyramid complex could be a manifestation of the profound changes in the ideology of kingship that took place between the 4th and 5th dynasties, changes that may have started during the reign of Userkaf's likely immediate predecessor, Shepseskaf. Some 1500 years after its construction, the pyramid complex was restored under Ramses II. During the much later Saite period (664–525 BC), it was used as a cemetery.

Question: Userkaf's pyramid was next to another pyrimad belonging to whom?
