The Sterling-Rock Falls Historical Society is a non-profit organization founded in 1959 by local citizens interested in preserving the heritage of the Sterling-Rock Falls area. To further this goal the Society established a museum to interpret, preserve and research local history. The museum is currently located on the grounds of the Dillon Home Museum.
In March of 2007 the Society purchased the Lincoln-Manahan Home, 607 E. 3rd Street, Sterling. This home is one of the oldest remaining homes in the area, dating back to 1847. It is also the home where Sheriff William Manahan hosted Abraham Lincoln during his 1856 visit to Sterling. After extensive restoration the home was dedicated July 18, 2011 as the Lincoln-Manahan Home Museum. For more information, please visit their website.
