1964 - BOSTON LIGHT Designated National Historic Site.

Boston Light was America's first light station (1716) and the last to be automated (1998). It is still staffed by the Coast Guard. The first lighthouse was destroyed by the British at the close of the American Revolution in 1776; the present lighthouse was built in 1783. Boston Light was designated a National Historic Landmark in 1964. Little Brewster Island is now part of the Boston Harbor Islands National Recreation Area.
