The Plymouth Antiquarian Society was founded in 1919 with the mission of preserving local history and historic sites in the Town of Plymouth. The Society owns and maintains three historic houses from different centuries - The 1677 Harlow House, The 1749 Spooner House, and The 1809 Hedge House, as well as an ancient Native American site - Sacrifice Rock. The Society welcomes the public to its historic properties for tours, exhibits, and programs. The historic sites serve as important cultural resources for investigating the story of everyday life in Plymouth from colonial times to the modern era. The Society offers a seasonal calendar of special events and programs on local history. Our achievements include ongoing preservation and maintenance projects, research and interpretation of local history, and educational programming for visitors, students and residents.
