Sleeping Beauty Castle at Disneyland Park.
Sleeping Beauty Castle is the fairy tale structure castle at the center of Disneyland Park and Hong Kong Disneyland. It is based on the late-19th century Neuschwanstein Castle, with some French inspirations (especially Notre Dame de Paris and the Hospices de Beaune).

Disneyland's Sleeping Beauty Castle at night, February 2005.
Opened July 17, 1955, the castle is the oldest of all Disney castles. Though it reaches a height of only 77 feet (23 m), it was designed to appear taller through a process known as forced perspective; design elements are larger at the foundation and smaller at the turrets. The castle initially featured an empty upper level that was never intended to house an attraction, but Walt Disney was not satisfied with what he viewed as wasted space, and challenged his Imagineers to find some use for the space.
Beginning April 29, 1957, visitors were able to walk through the castle and view several dioramas depicting the story of Sleeping Beauty. The original dioramas were designed in the style of Eyvind Earle, production designer for Disney's 1959 film Sleeping Beauty, and were then redone in 1977 to resemble the window displays on Main Street, U.S.A.. The walkthrough was closed for unspecified reasons in October 2001; popular belief claims the September 11th attacks and the potential danger that ensued played a major factor in the closing.
On July 17, 2008, Disney announced that the Sleeping Beauty Castle walkthrough would reopen in the style of the original Earle dioramas, enhanced with new technology not available in 1957. The walkthrough reopened on November 27, 2008 at 5:00 PM, drawing long lines going as far back as the Hub. Unlike previous incarnations, visitors who are unable to climb stairs or navigate the passageways of the Castle can still experience the walkthrough "virtually" in a special room on the Castle's ground floor. This room is lavishly themed, and presents the closed-captioned CGI walkthrough recreation on a high-definition TV. This same virtual recreation is included on the Sleeping Beauty 50th Anniversary Platinum Edition DVD.
It is a common myth that the Disney family coat of arms hangs above the archway to the castle. The Disney family coat of arms  is composed of three fleurs de lis whereas the coat of arms on the castle  is three lions passant in pale. The origins and meaning of the coat of arms on Sleeping Beauty Castle is unknown at this time.
It is known that the coat of arms was not originally on the castle but was placed there sometime between June 1965  and July 1965.
During the 50th Anniversary 
In celebration of Disneyland's 50th anniversary, the castle was repainted and five turrets were decorated with stylized crowns, each representing a decade in the park's history.
- The creation of Disneyland is represented by a pair of famous "Ears" peeking up over the horizon to see the wonders to come.
- "A World on the Move", otherwise known as the "New Tomorrowland" of 1967, is represented by rocket ships and accented by opalescent planets.
- The Blue Fairy represents the debut of the Main Street Electrical Parade.
- The Indiana Jones Adventure is represented by the evil Eye of Mara, guarded by snakes.
- The 50th Anniversary of Disneyland is represented by fireworks and Tinker Bell.

Sleeping Beauty Castle at Hong Kong Disneyland
Hong Kong's Sleeping Beauty Castle is a carbon copy of its sibling in California. The rooftops of the Hong Kong castle use a dark shade of blue while the US uses a lighter blue shade so the US rooftops can be seen more 'shiny', using the reflection of sunlight. In Hong Kong, the castle looks more medieval, with natural white and pink colors for the accents and cornice, while the US uses more golden accents, cornice and decorations, giving it a more fairytale look while day time. The Hong Kong castle is surrounded by fewer trees than California's so fireworks view from the plaza to the castle in Hong Kong is wider while California's view is blocked by tall trees.
During the 5th Anniversary 
In celebration of Hong Kong Disneyland's 5th Anniversary, Celebration in the Air, the castle had been transformed into Tinker Bell’s Pixie Dusted Castle. The castle is decorated by golden pixie dust, which sparkles and shimmers in the sun, and illuminates by night.
Logo usage 
As Sleeping Beauty Castle is a Disney icon, it and Magic Kingdom's Cinderella Castle have become the basis for the logo of Walt Disney Pictures, Walt Disney Television, Disney Music Group and Walt Disney Studios Motion Pictures. It was also heavily featured in advertisements for the Wonderful World of Disney, formerly shown on the Disney Channel.
