Aerial images chart how Disneyland has changed over the past 60 years These aerial pictures chart the incredible expansion of the Disney theme park empire, from the original Disneyland built in 1955 to the firm's latest U.S. attraction completed in 2001. The corporation now has theme parks dotted across the world attracting tens of millions of visitors a year. Attractions have sprung up in Europe, Hong Kong and a park is currently under construction in Shanghai. But it all began back in the 1940s after the exploits of Mickey Mouse as well as feature-length cartoons such as Snow White and the Seven Dwarfs, Dumbo and Bambi had made Walt Disney a household name.

The entire park was built in the space of a year at a cost of $17million Such was the success that many fans began writing to the company asking if it would be possible to have a tour of their studios in Burbank, California. Walt Disney, realising that a tour of a working film studio would probably come as a let down to any excited visitor, began working on the idea of a park that would offer entertainments for children and adults. When his daughters Diane and Sharon were young, Disney would take them to LA's Griffith Park every Sunday, where the children would enjoy play on carousels but the adults would sit on benches bored. First guests: Hollywood celebrities and their children race off to explore Snow White's castle on the opening day of the original Disneyland in Anaheim, California in July 1955 Dreaming of a place which would offer fun and entertainment for all, Disney first envisioned an eight-acre site which he would name Mickey Mouse Park. But as he began to plan large themed areas each offering a variety of attractions he realised he would need a far bigger space. While he was forced to place his plans on the back-burner during World War II, by 1954 construction was ready to begin at a 160 acre orange orchard in Anaheim, California with funding in place thanks to a deal with the television channel ABC. Completed in just one year at a cost of $17million, Disneyland initially boasted four themed areas - Adventureland, Frontierland, Fantasyland, and Tomorrowland - as well as Main Street USA and Snow White's Castle.

Entrance fee back then was a reasonable $1, today it will set you back a hefty $92. Despite a disastrous opening ceremony where the water fountains ran dry and women's shoes got stuck into soft tarmac, the attraction was an immediate success. But to Disney's annoyance businesses began springing up around the site. Disneyland effectively became boxed-in and having drained their financial resources on the construction, the company could not afford to buy up any more of the surrounding area. It was not until the 1980s that the company was able to buy up surrounding plots to the west of the park most significantly the site of the the Disneyland Hotel in 1989, the Pan Pacific Hotel which became Disney's Paradise Pier Hotel in 1995, and several properties north of the Disneyland Hotel in the mid to late 1990s.

These animated mechanical characters quickly became a staple feature of theme parks across the world. Walt Disney himself died in 1966, just missing the opening of the ever-popular Pirates of the Caribbean attraction in 1967. But by then the company's attention had shifted to Florida where construction was well underway on the building of the spawling Walt Disney World resort. With the first of the four Florida parks, named The Magic Kingdom, opening in 1971. This was followed in 1982 by the second Florida park named Epcot, dedicated to the celebration of human achievement. With a focus on technological innovation and international culture, it quickly became a top attraction and is now the third most visited theme park in the United States. The third of the Florida parks was Disney's Hollywood Studios which opened its gates in 1989. Dedicated to show business, with a distinct golden years of Hollywood theme it now pulls in around 9.7 million guests a year. The last of the Florida parks to open was Animal Kingdom, which at a sprawling 500 acres in size is the the largest of all the Disney parks by far. This attraction brings brings in slightly more visitors than Hollywood studios at 9.8 million a year. From there the company returned to its roots building their California Adventure park just a few miles away from the original Disneyland in Anaheim. Completed in 2001, it did not open to the universal praise Disney executives may have dreamed of. After a series of negative reviews, it is currently pulling in around 7.5 million guests a year compared to the original Disneyland which pulls in around almost 16million.
