In 1954, the first work was begun on Disneyland. One year later, on July 17, 1955, it was finished. This was the completion of a dream, the creator Walt Disney had had for twenty years. He had built it on a very flat piece of land. There had been nothing there except some fruit trees. The park includes many things that are unique. Them are lots of things that children love to visit. And adults enjoy them almost as much.
   There are many other lands at Disneyland. Main Street U.S.A shows the United States around 1900. Adventureland shows the primitive forests of Asia and Africa. For young children the most enjoyable place is probably Fantasyland. Older children have a great deal of fun at Tomorrowland. It would be possible to spend several days at Disneyland and still not see everything.
