East Charity Shoal Light stands in northeastern Lake Ontario near the Saint Lawrence River entrance, marking a hazardous shoal on the rim of Charity Shoal Crater. Built to prevent further groundings after repeated accidents, it joined a concrete offshore pier begun in 1934 with a cast-iron tower first used at Ohio’s Vermilion Light Station from 1877 to 1929. Installed in 1935, the exposed structure rises from a reinforced concrete pier and remains an active federal aid to navigation, now automated and powered by solar panels. Listed on the National Register of Historic Places in 2008, it entered private ownership in 2009 while staying under Coast Guard maintenance.
