The site of Bayswater Point State Park once contained Breezy Point, an expansive mansion built in 1907 by New York City banker Louis A. Heinsheimer. In 1925, the mansion was converted into a home for disabled children, and it was later used as a home for children with
intellectual disabilities before being placed for sale in the late 1980s. A parcel that was to become Bayswater Point State Park was purchased by the
Trust for Public Land in 1986. The mansion, which by that point had been damaged by fire, was demolished in 1987 prior to the land being given to New York State in 1988; only the
conservatory was left standing. Between 1994 and 1996, the Audubon Society conducted a research and restoration project at Bayswater Point, seeking to engage the public with the land's conservation. In early May 2010, the park was briefly closed to the public as a result of budget cuts, along with 57 additional state parks and historic sites. In 2015, an $80,000 improvement project to stabilize Sunset Lodge at the park was announced. ==Usage==
