Pyramid of Elefantine

The pyramid of Elephantine is part of a group of seven very similar small step pyramids, along with the pyramids at Edfu South, el-Kula, Naqada, Saujet el-Meitin, Seila, and Sinki. All of these were built far from the main centres of Egypt and are very poorly understood. The pyramid of Elephantine is located in the northwest part of the Old Kingdom city on the south end of the island of Elephantine in the Nile. The structure was discovered in 1907, but it could only be identified as a pyramid after excavations by the German Archaeological Institute in 1978–79.
