The 2 hectares (5 acres) historic site contains an interpretive centre, several historic buildings from the Dawn settlement, and two cemeteries; one of which holds Henson's gravesite. Informal tours of Henson's family home began in 1948, although the larger property was not converted into a museum until 1964, after several other related historical structures were moved onto the historic site. The museum was privately owned until 1988, when it was sold to Kent County.
