Southwest Ledge Light

Southwest Ledge Light is a three-story octagonal tower with a mansard roof and surrounding balcony, mounted on a circular iron foundation. The structure sits on a rocky outcrop at the entrance to New Haven Harbor and marks the main shipping channel to guide vessels safely.

The lighthouse was built in 1877 and introduced an innovative circular iron foundation design created by Major George H. Elliott to address challenging ice conditions. This design became influential for coastal construction projects of that era.

The lighthouse displays Second Empire architectural style through its ornate window surrounds, decorative eaves, and distinctive cast iron round-arch windows. These design elements create a distinctive appearance that sets it apart from other towers in the region.

The lighthouse continues to function as an active navigation aid marking New Haven Harbor and was automated in 1973 for unmanned operation. Visitors should note the structure sits on a rocky island and access depends on weather and tide conditions.

The original iron superstructure of the lighthouse was displayed at the Philadelphia Exposition of 1876 before being installed at this harbor location. This exhibition showcased the engineering innovation to a broad audience before the tower took its place guiding ships.
