Epcot is the second of four theme parks built at Walt Disney World in Bay Lake, Florida, near the city of Orlando. It opened as EPCOT Center (Experimental Prototype Community Of Tomorrow) on October 1, 1982, and spans 300 acres (120 ha), more than twice the size of the Magic Kingdom park. It is dedicated to the celebration of human achievement, namely technological innovation and international culture, and is often referred to as a "permanent World's Fair." In 2014, the park hosted approximately 11.45 million guests, ranking it the third most visited theme park in North America and the sixth most visited theme park in the world. The park is represented by Spaceship Earth, a geodesic sphere that also serves as an attraction. Epcot was known as EPCOT Center until 1994, when it was later renamed Epcot '94, then Epcot '95, now commonly known simply as Epcot.
