The Memphis Pyramid, initially known as the Great American Pyramid, formerly referred to as the Pyramid Arena and locally referred to as The Pyramid, was originally built as a 20,142-seat arena located in downtown Memphis at the banks of the Mississippi River. The facility was built in 1991 and was originally owned and operated jointly by the city of Memphis and Shelby County; Shelby County sold its share to Memphis in April 2009. Its structure plays on the city's namesake in Egypt, known for its ancient pyramids. It is 321 feet (98m, about 32 stories) tall and has base sides of 591 ft; it is by some measures the sixth largest pyramid in the world behind the Great Pyramid of Giza (456 ft), Khafre's Pyramid (448 ft), Luxor Hotel (348 ft), the Red Pyramid (341 ft), and the Bent Pyramid (332 ft).
