Cementland is an incomplete public art exhibit on the 54-acre site of a former cement factory just north of St. Louis, Missouri. The brainchild of sculptor Bob Cassilly, who also created St. Louis' City Museum, it contains giant concrete sculptures and obsolete machinery, and was planned to have navigable waterways, among many other features. The Cassilly family said that they had hopes to continue construction on the project, but after a fire in 2014, this seems unlikely. The site is currently closed to the public.
