Point Judith Lighthouse

Fl (3) W 15s🇺🇸Rhode Island, USOperational

The present octagonal granite tower at Point Judith stands 16 meters tall, with its focal plane at 20 meters. Its upper section is painted brown, contrasting with the white lower half, creating a distinct daymark. An earlier tower built in 1810 was destroyed by a hurricane in 1815. It was succeeded in 1816 by a second stone tower, which featured ten lamps and a revolving light. The current structure dates from 1856, replacing the 1816 tower. Ship captains requested a change from a horn to a whistle for the fog signal in 1871.

Why it matters: This lighthouse is listed on the National Register of Historic Places. Its location at the convergence of Narragansett Bay and Block Island Sound creates a busy waterway historically prone to navigational hazards.

Background
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, and was listed on the National Register of Historic Places in 1988.
