The Prudence Island Lighthouse, more commonly known locally as the Sandy Point Lighthouse, is located on Prudence Island, Rhode Island and is the oldest lighthouse tower in the state.[2][3][4] Sandy Point is nicknamed Chibacoweda, meaning "little place separated by a passage", because the location is a little more than one mile offshore.
