Great Captain Island Light

The Great Captain Island Light is a granite lighthouse situated on an island off the coast of Greenwich, rising about 51 feet tall. The structure combines granite and cast iron construction and dominates the western approach to Long Island Sound.

The original light station at this location was built from limestone but was replaced by the current granite structure in 1868. The tower served as an active navigation aid for ships until its deactivation in 1970.

The lighthouse sits on an island that holds special meaning for Greenwich residents as a place of reflection. The location brings together maritime heritage with how people today remember those connected to the community.

The island is reachable by seasonal ferry from Greenwich during warmer months, making it possible to visit for a day. The lighthouse interior is closed to visitors, but you can view the structure from the boat and spend time exploring the island.

The lighthouse shares architectural features with five other light stations in the region, revealing it was built as part of a coordinated coastal network. This family of similar towers reflects the unified approach to maritime navigation along this section of the Sound.
