The Greater Ridgewood Historical Society was established in 1975 by a group of local residents to prevent the demolition of the Vander Ende Onderdonk House. From 1975 until 1981, the GRHS raised funds to reconstruct the house which had been seriously damaged by fire, and in 1976, published a history of the greater Ridgewood area, entitled Our Community, Its History and People. With the help of Federal, State and local funds, the Onderdonk House was opened to the public in 1982. In 1977, the House and property were listed on the National Register of Historic Places, and in 1978, granted the same status on the New York State Register. The House was given New York City landmark status in June of 1995. House serves as a museum for a permanent exhibit on the archaeology of the Onderdonk site, as well as changing exhibits relating to history, the arts and culture. The Society also maintains a history and genealogical research library, and offers many cultural events annually, including: guided house tours, history lectures and programs, genealogy workshops, craft classes and special events, such as St. Nicholas Day and other Dutch celebrations. The history and location of the house provide a rich educational and cultural experience for visitors interested in colonial history, Dutch history in NYC, colonial architecture, history of NYC.
