Although badly ruined, few sites in Egypt are more impressive than Karnak. It is the largest ancient temple complex in the world, and represents the combined achievement of many generations of Egyptian builders. Karnak actually consists of several temples. One of most famous structures of Karnak is the Hypostyle Hall, a hall area of 5,000 m2 (50,000 sq ft). The 134 massive columns arranged in 16 rows supported a roof that has now fallen. At a height of 24 meters (80 feet) the 2 middle rows are higher than the others.
