Main Street, U.S.A. is the first "themed land" inside the main entrance of the many 'Disneyland'-style parks operated or licensed by The Walt Disney Company around the world.
Each Main Street, U.S.A. (except in Tokyo and Shanghai) has a train station above the entrance, while the park's centrally located castle stands at the end (at Disneyland Paris and in Hong Kong, Sleeping Beauty Castle; at the Magic Kingdom and in Tokyo, Cinderella Castle; in Shanghai, Enchanted Storybook Castle).
The area closest to the entrance, usually just past the train station, is called Town Square. At the far end of main street, around and in front of the castle is called, The Hub or Central Plaza.
Town Square is home to City Hall, in which the Guest Relations office is located. Further along Main Street, the names painted in the windows on Main Street serve as credits for some of the many people, Imagineers and others, who contributed in some way to the creation of Disneyland. Largely they appear as fictional businesses (gyms, realtors, dentists), and they often refer to a hobby or interest that the person honored. Ub Iwerks's window, for example, refers to his prowess with cameras. For Disneyland's 50th anniversary, on July 17, 2005, a first-story window on each Main Street was unveiled with a dedication to all the cast members (employees) who had worked for Disney throughout the years. The streets are paved with resilient asphalt, a type of asphalt containing rubber, to prevent aching of feet. In July 2015, Disneyland expanded their Main Street U.S.A. with a Main Street Arcade in honour of their 60th anniversary.
The Hub is a plaza area in front of the castle at the end of Main Street. Here, one will find the entrances to most of the lands at the Magic Kingdom style parks. Usually, from left to right, a person will find the entrances to: Adventureland (or similar area); Frontierland (or similar area. At the Magic Kingdom, the entrance will be to Liberty Square which almost acts as a time traveling area from the 20th century of a U.S. "main street" to the 18th century of Liberty Square to the Wild West feel of Frontierland); through the castle, at all parks one will find Fantasyland (there will usually be a side entrance to the land as well as the castle entrance); and to the right will usually be Tomorrowland (or similar area).
