The museum complex opened in 1977 as  the Iron Range Interpretive Center with 34 exhibits and was renamed in 1984 as Ironworld USA. In 2009 it became the Minnesota Discovery Center. It was built to celebrate the immigrants who built Minnesota's Iron Range mining region, including Italians, Finns, and Yugoslavs. It was supposed to draw tourists from around the state and other parts of the U.S., but in the late 1990s was struggling to live up to attendance expectations. Due to shifting ground on the property with mine shafts beneath it, the tourist attraction faced a $2 million to $7 million cost in 2004  for filling and shoring up its foundation or to do complete reconstruction. It is located on the old Glen Mine property where there are abandoned mine shafts. The Center include a 1920s trolley that travels along a "picturesque" railway that winds around the Pillsbury mine pit and Glen mine disembarking at Wilpen Train Depot. There is a renovated 1905 Hill's Finn Boarding House. There is also the Pellet Pete 19 hole mini-golf course. The Ironworld Museum has two floors of "exhibits about geology, mining, immigration and other aspects of the industrial and cultural history of the region," including  the taconite mining process and the evolution of the industry on the Iron Range.
