Jonathan Scranton, Volney Pierce, and John Wilcox were contracted to build the new 65-foot (20 m) octagonal brownstone tower.

In 1990, it was added to the National Register of Historic Places and is significant for its "superior stone work in the tapering brownstone walls".

[2][3] Out of a need for a lighthouse to mark the Old Saybrook harbor, the government paid $225 for William Lynde's land at its entrance to erect a light.

[6] The contract for the lighthouse was awarded to Jonathan Scranton, Volney Pierce, and John Wilcox of Madison, Connecticut, on August 18, 1838.

[5] In 1852, a fourth-order Fresnel lens from Barbler and Fenestre replaced the original ten lamps and 9-inch (230 mm) reflectors.

[6] Lynde Point Lighthouse used whale oil until 1879 when it switched to kerosene, it was electrified in 1955 and fully automated by the United States Coast Guard in 1978.

[6] Templeton writes, "Lynde Point exhibits superior stone work in the tapering brownstone walls.

Lynde Point also is significant as part of the federal government's early efforts to improve aids to navigation in Long Island Sound, when the mouths of important harbors and rivers were among the first sites chosen for lighthouse appropriations.
