On the National Register of Historic Places, the Foshay Tower has been on a popular and sentimental landmark for Minnesota since opening in 1929. The only building in the world modeled after the Washington Monument, the Foshay Tower was built by multi-millionaire real estate developer Wilbur B. Foshay in 1929 and was instantly heralded as a modern, art deco masterpiece. Foshay was a larger than life character and it’s reflected in the building that bears his name. Painstakingly restored and transformed into a W hotel in 2008, today visitors to the museum, located on the tower’s 30th floor, can follow the creation of this unique building and the man behind it; then venture out onto the only open-air observation deck in Minneapolis/St. Paul for panoramic, 360-degree views of the Twin Cities.
