Can you buy Disneyland tickets right now: Disneyland Park is the first of the two themed Parks built in Anaheim, California at Disneyland Resort opened on 17th July 1955. Under Walt Disney’s direct supervision, it is the only theme park to be designed and completed. It was originally the only attraction on the property; its official name was changed to Disneyland Park to distinguish it from the expanding complex in the 1990s. It was the first Disney theme park.
On Sunday, July 17, 1955, Disneyland was dedicated at a “International Press Preview” event that was only open to invited guests and the media. Although 28,000 people attended the event, only about half of them were invited, with the rest having purchased fake tickets or sneaking in by climbing over the fence.
It was open to the public the next day, with twenty attractions. The Special Sunday events, including the dedication, were anchored by three of Walt Disney’s Hollywood friends: Art Linkletter, Bob Cummings, and Ronald Reagan.
