E.P.C.O.T did have its own amusement park pictured here. The park is an amusement park due to some contradictory themes, which is why an "amusement" park differs from a "theme" park. Many of the attractions are based upon the American Space Program. If you look closely, the circus happens to look very much like the original artwork for Space Mountain when it was designed and developped during Walt Disney's lifetime at the end of the 60's. The amusement park is surrounded by a Casey jr like train and is connected to other E.P.C.O.T areas through a PeopleMover line. The amusement park was dedicated to E.P.C.O.T residents. The themepark (which eventually was called the Magic Kingdom) was at the contrary dedicated to the tourists.
