The Great Pyramid at Giza is considered the first wonder of the world, according to the Travel Channel. It is the oldest of the Seven Ancient Wonders of the World, and it is the only structure from that list that is still in existence.

The pyramid was built in about 2560 B.C. for an Egyptian pharaoh named Khufu, according to the Travel Channel. The pyramid was one of three constructed in Giza, which is now part of Cairo, Egypt. The Great Pyramid is almost 480 feet tall, and each side is about 755 feet long. The pyramid includes about 2.3 million bricks that each weigh about 4,000 pounds.
