| The Point Judith Light is located on the west side of the entrance to Narragansett Bay, Rhode Island as well as the north side of the
 eastern entrance to Block Island Sound. The confluence of two
 waterways make this area busy with water traffic and the waters around
 Point Judith are very cold and dangerous. Historically, even with
 active lighthouses, there have been many shipwrecks off these coasts.
 
 Three light structures have been built on this site. The original
 35-foot (11 m) tower, built in 1810, was destroyed by a hurricane in
 1815. It was replaced in 1816, by another 35-foot stone tower with a
 revolving light and ten lamps. The present octagonal granite tower was
 built in 1856. The upper half of the tower is painted brown and the
 lower half white to make the light structure a more effective daymark
 for maritime traffic. In 1871, ship captains asked that Point Judith's
 fog signal be changed from a horn to whistle. This change
 distinguished the Point Judith light from the Beavertail Lighthouse,
 which used a siren to announce fog. A whistle could also be heard more
 distinctly over the sounds of the surf in the area. Point Judith Light
 was automated in 1954.
