Founded in 1966, the Bethel Historical Society provides visitors with a doorway to northern New England's varied and colorful past. The Society's Regional History Center, established in 1999, operates year-round from two adjoining properties: the 1821 O'Neil Robinson House and the 1813 Dr. Moses Mason House. The Regional History Center's collections include a wide range of materials documenting the history of Maine, New Hampshire, and Vermont, with major concentration on western Maine and the White Mountains. The Center offers more than a dozen period rooms and exhibition galleries as well as areas for craft demonstrations, research library operations, and Museum Shop sales. It also provides lectures, conferences, special events, educational activities and publications for members and the general public.
