City Museum is a play house museum, consisting largely of repurposed architectural and industrial objects, housed in the former International Shoe building in the Washington Avenue Loft District of St. Louis, Missouri, United States.Opened in 1997, the museum attracted more than 700,000 visitors in 2010.The City Museum has been named one of the "great public spaces" by the Project for Public Spaces, and has won other local and international awards as a must-see destination. It has been described as "a wild, singular vision of an oddball artistic mind" and compared to the similarly individualistic Museum of Jurassic Technology in Los Angeles.HistoryCity Museum was founded by artist Bob Cassilly and his then-wife Gail Cassilly. The museum's building was once an International Shoe Company factory and warehouse but was mostly vacant when the Cassillys bought it in 1993. Construction began in January 1995.The City Museum opened to the public on October 25, 1997. Within two years, it was drawing 300,000 visitors a year.The museum has since expanded, adding new exhibits such as MonstroCity in 2002, Enchanted Caves and Shoe Shaft in 2003, and World Aquarium in 2004.
