This imposing lighthouse has spectacular views from its base of the nearby Elizabeth Islands and of Martha's Vineyard, across Vineyard Sound. The 42-foot cast-iron tower, lined with brick, was built in 1876 with a stationary light. It shines red to indicate dangerous waters or white for safe passage. Since the light was automated in 1985, the adjacent keeper's quarters have been the headquarters of the Coast Guard group commander—a fitting passing of the torch from one safeguarder of ships to another. The interior is open to the public through scheduled tours arranged by the U.S. Coast Guard.
