Qasr Ibrim (Arabic: قصر ابريم‎) is an archaeological site in Lower Nubia, located in the modern country of Egypt. The name is derived from the nearby village of Ibrim, on the east bank of the Nile. The site has a long history of occupation, ranging from as early as the eighth century BC to 1813 AD, and was an economic, political, and religious center. Originally it was a major city perched on a cliff above the Nile, but the flooding of Lake Nasser after the construction of the Aswan High Dam transformed it into an island and flooded its outskirts. Qasr Ibrim is the only major archaeological site in Lower Nubia to have survived the Nile floods.
