The earliest I have for Black Point is 1895 and that only includes the Windswept property. I have no history on the additional 42 acres that was acquired in 1989 prior to that, except for a report of a grumpy old man who lived in a shack down there and used to chase off kids with a shotgun.
The Castiglione brothers sold the property in 1952 to the Lownes Famiily, who never occupied it. It sat vacant, was vandalized and had 3 fires in 3 years.
In 1974(or maybe 1980) the 18 acre Windswept property was purchased by the Rhode Island Department of Environmental Management.
In 1989, the State of RI added to the Black Point property. From ‘Save the Bay”, May/June 1989, “Making good on a 1988 campaign promise to acquire 42 acres of shoreline property at Black Point in Narragansett and retain it as open space, Governor Edward DiPrete announced on May 18 that the state will spend $6.4 million to take the land though condemnation”. The property was “slated for development by the Dowling Corporation, which planned to build 80 condominiums on the property.”
The purchase of this property was a hard-won victory and at the time one of the greatest public access battles of all time.
(Was Black Point named after the SS Black Point, a merchant marine ship sunk by German submarine U-853 off Pt. Judith on May 5, 1945 while carrying coal to Boston? This was the last ship sunk by German U-boats. http://www.usmm.org/blackpoint.html)
