Keswick was a small community that began in 1872 when Reverend John Lawrence moved here from Keswick, New Brunswick, Canada. A gristmill was built nearby, and a post office operated from September 1889 until November 1910. At its peak, Keswick's population was 200, but by 1910 it had dropped to 40. Today, only the Keswick Methodist Church remains, located on County Road 633 between Bingham and Suttons Bay.
