Lovell's Island Rear Range Light (Mass.)

Boston Harbor
See also Lovell's Island Front Range Light
The range lights on Lovell's Island were established to help mariners using the South Channel of Broad Sound. The lighthouses were 400 feet apart and a seven-foot high walkway connected the lighthouses, the keeper's house, the woodshed and the oil house. The lighthouses were destroyed to make room for the expansion of military facilities on the island; today all that remains is the oil house.
