Located in the heart of Le Mars, Iowa, the Plymouth County Historical Museum is housed in the historic Old Central High School, built in 1905 and expanded in 1924 and 1952. We moved in 1983 to save the historic building from demolition. Whether you're visiting for a community event or exploring on a regular day, stop by and experience our engaging five-story museum.
