It was listed in the National Register on August 8, 1983. The first light marking Ashtabula's harbor was built in 1836, a short hexagonal wooden tower standing on a wooden crib just off the eastern pier. This used the oil lamps typical of the time and remained in service until replaced by a new tower on the west pier, a pyramidal tower with clapboard sides. This change was prompted by changes in the harbor configuration. The new light was equipped with a fourth-order Fresnel lens, exhibiting a red light. Keepers lived in a frame house in town. This tower was moved in 1882 but remained in service.
