The largest and most popular shopping mall in the United States is the Mall of America. It is in Bloomington, Minnesota, in the north-central part of the country near the twin cities of Minneapolis and Saint Paul. It opened in nineteen ninety-two and cost six hundred and fifty million dollars to build.
    Each year about forty million people visit the Mall of America. Mall officials say four out of ten people who visit have traveled long distances. Many people stay several days when they visit the mall. There are more than forty hotels within eight kilometers.
    The Mall of America has more than five hundred and twenty stores. It also has more than fifty places to eat. If you lined up all the stores side by side, they would cover a distance of almost seven kilometers. If you stayed only ten minutes in each store, it would take over eighty-six hours to complete your visit.
    When the owners designed the mall, they wanted it to be more than just a place to shop and eat. So they made entertainment a big part of their plan. The Nickelodeon Universe is an indoor theme park. It has more than twenty-five rides including several roller coasters.
    Another popular part of the mall is the Underwater Adventures Aquarium. It holds about five thousand sea animals. Visitors walk through a ninety-one meter glass tube. Sharks and other ocean animals swim above and beside you as you walk through the tube.
    Some people who visit the Mall of America have other things in their mind besides sharks, shopping, eating and roller coasters. They go to the Chapel of Love to be married. More than five thousand couples have had their weddings at the Mall of America.
