MARENGO – Residents can learn about a historical World War II-era camp’s connection to the Marengo Curtiss Candy Farms today.

The Marengo Society for Historic Preservation is hosting the free program at 2 p.m. inside Marengo City Hall, 132 E. Prairie St., about Rockford’s Camp Grant, one of the largest U.S. Army training centers in World War I and World War II.

The 18,000-acre camp later served as a prison for World War II German prisoners of war, who were transported to work at the huge Curtiss Candy Farms in Marengo. Terry Dyer of Roscoe will provide the presentation.
