Situated right outside Luxor, Karnak Temple is the largest ancient religious site in the world. An impressive avenue of ram-headed sphinxes connects it with Luxor Temple. Karnak is a place of records: everything here seems to be the biggest and tallest. Its scale defies description. The first pylon (gate) alone is 42 metres high (like a 14-storey building) and 118 metres wide. Ancient Egypt must have been in awe of its builders.
