For more than two millennia, Heliopolis was one of the most important spiritual centres of Ancient Egypt. The site is greatly threatened by modern construction and garbage dumps and little is known about its cult topography. As such, the BA Antiquities Museum is organizing a joint lecture that will be delivered by Dr. Aiman Ashmawy, Head of the Egyptian Archaeological Sector of the Ministry of Antiquities, Co-Director of the Heliopolis Project; as well as Dr. Dietrich Raue, Curator of the Egyptian Antiquities, Georg Steindorff Museum, the University of Leipzig, and Co-Director of the Heliopolis Project. They will discuss The Heliopolis Project, a joint Egyptian-German mission of the Ministry of Antiquities of the Arab Republic of Egypt, the George Steindorff Egyptian Museum of the University of Leipzig and the Uni¬versity of Applied Sciences Mainz, which started systematic excavations in 2012. One of the most important excavations was along the central west-east axis of the temple, with evidence of sanctuaries and sculptures of the 2nd and 1st millennium BCE. Most findings bear, despite their fragmentary status, interesting aspects and may help to shed light on the hither to almost unexplored temple, as well as on the eras of Senusret I, Ramesses II, Psamtek I and Nectanebo I.
