Kalabsha Temple was another monument saved from the rising waters of Lake Nasser along with Abu Simbel and the temples at Wadi as-Subua. Kalabsha is a Ptolemaic-era temple dating from the reign of Augustus, around AD20. Its location at the very edge of Egyptian territory with that of Nubia meant that it is dedicated to more the Egypto-Nubian god Horus-Mandulis, as well as Isis and Osiris. A stone ramp leads up from Lake Nasser to the monument which sits in stark surroundings in what would have been desert until recently. There is a Hypostyle Hall and several chambers to explore before reaching the roof, from where there are excellent views back towards Aswan.
