The first royal monument that was built at Abu sir was Userkaf's, Solar Temple. Several kings of Userkaf's dynasty would not only follow his example and build their own Solar Temple at Abu sir (even though only Userkaf's and Niuserre's have been located), they would also use the site for their funerary monument. One important factor that must have played an important role in the choice of this site is the presence of Abu sir Lake, which made the site easily accessible by boat. King Userkaf, the founder of the 5th Dynasty, chose this site to build his solar temple. Several of his successors would not only follow his example and build their own solar temples, they would also prefer this site for their burial.

It's a private visit with extra fees needs special permissions (10 - 14 days).

The last solar temple was apparently built by Menkauhor, towards the end of the 5th Dynasty, although it is not found yet, it also seems that with the last solar temple, the kings of Egypt lost interest in Abu sir as a burial ground.

The site continued to be used, however, by the Memphite nobility until the end of the pharaonic era. royal pyramids of Abu sir break the diagonal alignment: the unfinished pyramid believed to have been started by Shepseskare somewhere halfway between Sahure's pyramid and Userkaf's Solar Temple; and the pyramid of Niuserre that was inserted between Sahure's and Neferirkare's pyramids in such a way that the unfinished causeway and Valley Temple that were intended for Neferirkare's monument were diverted to Niuserre's.

A small pyramid south of the pyramid of Neferirkare was probably intended as his satellite pyramid but works were halted, presumably at his death and the small pyramid was later on converted into a funerary monument for the queen-mother, Khentkaus II, with its own mortuary temple. Two small pyramids to the east and southeast of Neferefre's pyramid need further examination. Thus far they are assumed to be queen's pyramids, but this is not certain and even if they were, it is not known for which queens they. site is closed and it is a must to get a special permission to explore the charm of this pure place.
