The Pyramid of Sahure (in ancient Egyptian Kha-ba Sahura (The rising of the "ba" spirit of Sahure)) is a late-26th-to-25th century BC pyramid complex built for the Egyptian pharaoh Sahure of the Fifth Dynasty. Sahure built the inaugural pyramid in Abusir after his direct predecessor, Userkaf, built his sun temple in the same area. Sahure's successors, Neferirkare Kakai, Neferefre, and Nyuserre Ini all built their monuments in the vicinity. The site was first properly excavated by Ludwig Borchardt between March 1907 and 1908, who penned the seminal work on the topic "Das Grabdenkmal des Königs Sahu-Re" between 1910 and 1913.
