Who built the largest tomb in the world?

The largest tomb in the world is the Great Pyramid of Giza, built for the Egyptian pharaoh Khufu, also known as Cheops. Constructed around 2580–2560 BC, it is the oldest of the Three Pyramids of Giza and the largest of the pyramids in Egypt. The Great Pyramid originally stood at 146.6 meters (481 feet) and was the tallest man-made structure for over 3,800 years. Its construction involved thousands of workers and sophisticated engineering techniques for the time.
