The Houf Pyramid is the largest pyramid in Egypt and one of the Giza Pyramids. The height of the tower is 146.59 meters. Due to the weathering, the top of the tower has been peeled off for 10 meters. Now it is 136.5 meters high. The tower body is made of 2.3 million huge stones, weighing 1.5 to 160 tons of different sizes and weighing about 6.84 million tons. It is the largest pyramid ever found in Egypt and the oldest and only remaining building in the seven wonders of the ancient world. Because the surface of the pyramid is ladder-like, many tourists will climb a section in the lower part of the pyramid.
