The Lincoln Park Preservation Alliance is a non-profit organization dedicated to the preservation and protection of Lincoln Park's historic resources, working to protect Lincoln Park's historic sites through education, advocacy, research, tours, workshops, and lectures. The alliance also collaborates with the Lincoln Park Historical Society and Historical Commission. In February 2004, the Lincoln Park Preservation Alliance established the former Lincoln Park Post Office--now the Lincoln Park Historical Museum--as the community's first site listed on the National Register of Historic Places.
