Green's Ledge Lighthouse, Long Island Sound, Norwalk, Fairfield County, CT

Significance: Green's Ledge Lighthouse, built 1902, is significant as an example of a pre-fabricated, conical, cast-iron light tower built on a cylindrical cast-iron and concrete foundation. That design was developed by the U.S. Lighthouse Board in 1873 as a less expensive alternative to masonry construction for the marking of submerged hazards. The materials, construction, architectural detail and interior finish at Green's Ledge Lighthouse reflect the standardized design for this type of structure. This lighthouse is also significant for its role in the navigational aids system in Long Island Sound, where it warns of a submerged rock ledge at the western boundary of the Norwalk Islands group.
