Legoland Billund, the original Legoland park, opened on 7 June 1968 in Billund, Denmark. The park is located next to the original Lego factory and Billund Airport, Denmark's second-busiest airport. Over 1.9 million guests visited the park in 2011 and since the opening more than 50 million guests have visited the park. This makes Legoland the largest tourist attraction in Denmark outside Copenhagen. The Legoland parks that have since been built are modelled upon Legoland Billund, most noticeably the Miniland area, which is made up of millions of plastic Lego bricks.
