De to poor construction and a storm, it collapsed in 1828. In 1829, a new lighthouse was built north of the m

The first official lighthouse keeper, Colonel George McDougall, Jr., served from 1825 until his death in 1842. The green flashing light that was automated in 1933 may be seen for seventeen miles. The two-story brick lighthouse keeper's house, with its hipped gable roof and pointed gothic porch, was built in 1874. Today, a Coast Guard station and the lighthouse watch over one of the busiest waterways in the world.
