Giza is an Egyptian city on the west bank of the Nile, near Cairo. The Giza Plateau is home to iconic Egyptian monuments, including 3 tall pyramids built as royal mausoleums around the 26th century B.C. The largest, the Great Pyramid, is King Khufu’s tomb. The Great Sphinx is a vast sculpture of a man’s head on a lion’s body. The Solar Boat Museum displays a restored cedar barge found buried near the Great Pyramid. Giza is most famous as the location of the Giza Plateau: the site of some of the most impressive ancient monuments in the world, including a complex of ancient Egyptian royal mortuary and sacred structures, including the Great Sphinx, the Great Pyramid of Giza, and a number of other large pyramids and temples. Giza has always been a focal point in Egypt's history due to its location close to Memphis, the ancient Pharaonic capital of the Old Kingdom. Its St. George cathedral is the episcopal see of the Coptic Catholic Eparchy of Giza. The Great Pyramid of Giza at one time was advocated (1884) as the location for the Prime Meridian, a reference point used for determining a base longitude.
