Temple of Karnak.
Also known as Ipet-isut. It is a city of temples built over 2000 years and dedicated to the Theben triad of Amun, Mut and Khonsu. It is the mother of all religious buildings, the largest ever made and a place of pilgrimage for nearly 4,000 years. It covers about 200 acres 1.5km by 0.8km. Karnak is the home of the god Amun who was an insignificant local god until the 12th dynasty when Thebes became the capital of Egypt. He was represented in his original state as a goose and later as a ram, at the height of his power he was shown as a human with a head dress of feathers - all that remained of the goose.
