The Bubasteion was a Ptolemaic and Roman temple complex dedicated to Bastet in the cliff face of the desert boundary of Saqqara. In Arabic the place is called Abwab el-Qotat ("The Gates of the Cats").
Proper investigation of the site was begun in 1976 by Alain-Pierre Zivie and the first excavations began in 1980. In 1986, the Mission Archéologique Française du Bubasteion (MAFB), was founded, which has overseen all investigations of the site since then.
In the second half of the 18th Dynasty, high dignitaries created rock-cut tombs for themselves in this area, which were later reused as cat-catacombs.
