The Bayport Heritage Association was formed in 1983 and is dedicated to the preservation of the history of Bayport. The association has an extensive collection of archival photographs, vintage clothing, artifacts and books. Through the years, the group has been particularly active in the restoration of Meadow Croft, a John Ellis Roosevelt summer home and now a historical museum on the border of Bayport and Sayville. The association provides lectures and resources- educational, historical, environmental and social programs and services for the community and interested public. In June 2018, Blue Point joined the Association to include both communities.
