The only plausible precedent for Userkaf's sun temple was the temple associated with the Great Sphinx of Giza, which may have been dedicated to Ra and may thus have served similar purposes. In any case, Userkaf's successors for the next 80 years followed his course of action: sun temples were built by all subsequent Fifth Dynasty pharaohs until Menkauhor Kaiu, with the possible exception of Shepseskare, whose reign might have been too short to build one. Userkaf's choice of Abusir as the site of his sun temple has not been satisfactorily explained, the site being of no particular significance up to that point. Userkaf's choice may have influenced subsequent kings of the Fifth Dynasty who made Abusir the royal necropolis until the reign of Menkauhor Kaiu.
