The New Haven Preservation Society, Inc. was incorporated in 1989 for the primary purpose of saving historically significant buildings, documents and artifacts relating to the history of the New Haven, Missouri community.

The Preservation Society is located in the Old Grade School Building, located at 810 Maupin Avenue in New Haven.  The building, which was erected in 1883, was purchased by the society on June 30, 1989. has undergone extensive renovation by the Preservation Society.  Meeting rooms are available for community use and private rentals.  Two museums, an archive and research room are also housed in the building.  The archive contains a large collection of historic documents and memorabilia.  The museums are popular with visitors to New Haven, school groups, scouts, civic organizations and individuals who are interested in local history.  Monthly meetings of the New Haven Preservation Society are held in the building.

The organization is supported by membership dues and private donations.  Most members reside in the New Haven area, with some supporting members living outside the area. 

Current projects include the restoration of the 130 year old Anna Bell Chapel, and ongoing upgrades to the Old School.  In addition to sponsoring several community events, such as a popular Candlelight Christmas House Tour, members also volunteer and assist other organizations involved in community activities.
