The ancient Mexicans (and Egyptians) - for religious reasons.
This is the pyramid of Khufu also known as the Great Pyramid of Giza or the pyramid of Cheops [his Greek name] and is one of the three pyramids at Giza. It is the only existing Seven Wonders of the Ancient World and the biggest pyramid built in Egypt.
The three main pyramids of Giza belong to the Pharaohs of ancient Egypt: the Great Pyramid, built for Pharaoh Khufu (Cheops), is the largest; the Pyramid of Khafre, built for his son Pharaoh Khafre, is slightly smaller; and the Pyramid of Menkaure, the smallest of the three, was constructed for Pharaoh Menkaure. These pyramids were part of a complex that served as monumental tombs and symbols of the pharaohs' power and divine status.
