Aptly called Ipet-Sut `The Most Select of Places` by the ancient Egyptians, Karnak Temple was the most important temple in Thebes (modern Luxor), in Upper Egypt. This was where the cult of the great god Amun of Thebes was conducted. As such, it was extremely wealthy and its priesthood held great political power. Karnak and other areas of ancient Thebes—including Luxor, the Valley of the Kings, and the Valley of the Queens—were collectively designated a UNESCO World Heritage site in 1979. Karnak covers more than 100 hectares, an area larger than some ancient cities.
