From 1961 to 1981, the city of Bloomington was home to most of the major sports teams of Minnesota. In 1961, after the completion of Metropolitan Stadium in 1956, both the Minnesota Twins and Minnesota Vikings began regular-season play. Although Metropolitan Stadium was originally built for the American Association Minneapolis Millers, a minor league baseball team, Metropolitan Stadium was renovated and expanded for Major League Baseball and the National Football League. The first Twins game was held on April 21 (Washington 5, Twins 3) and the first Vikings game was held on September 17 (Vikings 37, Chicago Bears 13). On August 21, 1965, The Beatles played Metropolitan Stadium, their only stop ever in the Minneapolis-St. Paul Metropolitan Area. In 1967, with the expansion of the National Hockey League, the Metropolitan Sports Center was built near the site of the Metropolitan Stadium and the Minnesota North Stars began play later that year.
