Saint Louis County Heritage and Arts Center 3.6 (reviews)

You haven't seen Duluth until you've explored the St. Louis County Heritage and Arts Center's Historic Union Depot, better know as simply the Depot. This former Union Railroad Depot was built in 1892 by the Boston firm of Peabody, Stearns and Furber. By 1910, the Union Depot was serving seven different rail lines with up to 5,000 people passing through its doors daily. In 1971, this beautiful landmark, in the French Norman architectural style, was listed on the national register of historic places.
