Explanation:

[STC002034] At the largest sculpture garden in the United States, which is located near Minneapolis, you can let your creativity run wild. The Minneapolis Sculpture Garden at the Walker Art Center, which was initially conceived of and constructed by Edward Larrabee Barnes in 1988, has developed into a focal point for the city. Its most famous feature is ‘Spoonbridge and Cherry,’ which is… well, just what it sounds like: a giant spoon topped with a cherry, built in 1985 by artist Claes Oldenburg and his wife, Coosje van Bruggen. ‘Shadows at the Crossroads,’ ‘Black Vessel for a Saint,’ and ‘September Room,’ to name just a few of the garden’s other notable works, are also among its highlights. It was the largest urban sculpture garden in the United States when it first opened, and it easily maintains that title. It is now sprawled across a 19-acre property, making it significantly larger in size than its initial version.
