Prudence Island Light, also known as Sandy Point Lighthouse, is an active aid to navigation located on Sandy Point on the east side of Prudence Island in Narragansett Bay, Rhode Island. It is the oldest lighthouse tower in the state and one of the few lighthouses in the country to retain its original birdcage lantern.The lighthouse was constructed in 1823 and originally sat on a dike off Goat Island farther south in the Bay, where the Newport Harbor Light stands today. In 1851, it was transported to Prudence Island where it remains. The lighthouse is a 28-foot-tall octagonal granite tower with a white exterior and a black lantern. It is surrounded by a two-acre property that includes a small keeper's dwelling and a boathouse.Prudence Island Light is only accessible by boat and is not open to the public. It is still an active aid to navigation, with a modern beacon producing a green flash every six seconds. The lighthouse is listed on the National Register of Historic Places and is managed by the Prudence Island Conservancy.
