The largest of Luxor’s temples, Karnak was one of the most sacred sites in ancient Egypt. It marked the ascendancy of Thebes (present day Luxor) as the capital of the New Kingdom, with construction beginning in the 16th century BC. Most subsequent rulers tinkered with the complex so it represents a great crash course in different pharaonic styles.
The major site here is the Temple of Amon, the largest place of worship ever constructed. There the Great Hypostyle Hall, which was once roofed, dwarfs visitors with its dozens of colossal columns reaching 25 yards (23 meters) into the sky.
Other highlights include the serene sacred lake, gargantuan statues of rulers and gods, as well as the best selection of obelisks in Egypt.
Karnak is on the northern edge of Luxor’s East Bank. While the distance can be covered on foot, you’re better off taking a taxi, or one of the buses which leave from Luxor Station. There are Sound and Light shows in the evening.
