Deer Island Light

Deer Island Light is a navigation lighthouse in Boston Harbor equipped with a modern steel framework and LED lighting technology. The structure broadcasts a light signal visible across the water and also operates a radio signal that ships can activate through VHF channels.

The first beacon at this location was built in 1832 as a stone structure, followed by a larger tower completed in 1890. This expansion reflected the growing ship traffic through Boston Harbor.

The station was home to lighthouse keepers who lived and worked in isolation, maintaining the light and keeping watch over passing ships. This solitary work shaped life on the island for generations.

The island location makes access difficult from land, so visiting requires a boat trip across the harbor. It is wise to check weather conditions before planning a visit, as visibility from the water varies greatly depending on season and time of day.

Between 2015 and 2016, the entire structure was moved 100 feet south to place it on a secure foundation. This remarkable feat preserved the landmark from erosion risk and ensured its continued use as a navigational aid.
