About Columbia County Lighthouses Lighthouse

Constructed in 1874, this square cylindrical brick lighthouse stands 9 meters tall. Its lantern and gallery are black, contrasting with the unpainted red brick tower and white trim. The structure includes an attached two-story mansard-style keeper's house. Originally built to mark a shoal between Hudson City and Athens, it emits a single green flash every 2.5 seconds. The lighthouse has undergone significant preservation efforts since the 1980s, including repairs to its foundation and the installation of a solar power array in 2019 after an interior power cable failed. It was named one of New York State's 'Seven to Save' in 2020 due to its endangered status.

Why it matters: This lighthouse marks a shoal in the Hudson River, which is a hazard to river traffic. It is an architecturally distinctive example of brick lighthouse construction in the region.
