The "Happiest Place on Earth" celebrated its 63rd anniversary on July 17, 2018. On that day in 1955, Disneyland opened it's doors for the first time.
The original Disney theme park rang in another year during its first-ever Pixar Fest. The "Happiest March on Earth" included 63 Disney characters, Dapper Dans barbershop quartet, and the Disneyland Resort Ambassadors marching down Main Street U.S.A.
Disneyland is the only theme park designed and built under the direct supervision of Walt Disney. Construction cost $17 million and took exactly one year to complete.
