The Chester Rock Light was constructed in 1889 as part of a $15,000 appropriation by Congress that included several other beacons.

Originally constructed as a 21-foot (6.4 meter) tall wooden hexagonal pyramidal tower, the Chester Rock Light had a black lantern with a 6th order Fresnel lens.

[5][6] The light's foundation rested upon the river bottom and was a 15-foot (4.6 meter) square crib that was made of yellow pine timbers and sheathed with planks.

[9] According to the Annual Report of the Lighthouse Board, the tower was struck and carried away by a barge being towed by Sachem, a tugboat, on May 10, 1912.

[11] Completed on October 22, 1912, the replacement skeletal tower was a pyramidal steel structure on a concrete base that held its oil internally.

[2] In 1931, an article in The Day noted that the skeleton tower was "in recent years" converted to automatic gas beacons.
