It is located in Dyersville, Iowa, within Dubuque County. Universal Pictures built the baseball diamond in 1988 on two farms a few miles outside Dyersville, Iowa, for the 1989 film Field of Dreams. When production completed, the baseball diamond created for the movie was left behind. Most of the baseball field, including the diamond and the adjacent house, was on a farm owned by the Lansing family, but the left and center field were on an adjacent property owned by the Ameskamp family. The field was built across the two properties because the producers wanted to place the field in a location where sunset shots would have a clear line-of-sight.
