Luxor is often called the world’s greatest open-air museum and there might be nothing in the world that compares to the scale and grandeur of the monuments that have survived from ancient Thebes. After the pyramids of Giza, Karnak is Egypt’s most important pharaonic site. Excavations over the years have gradually uncovered the original structure of the temple complex, which was built over a 1,300-year period. Luxor Temple is an elegant example of Pharaonic temple architecture. The temple was largely completed by the 18th-Dynasty pharaoh Amenhotep III and added to during the reign of Ramses II in the 19th Dynasty.
