With the exception of Mount Desert Island’s Bass Harbor Head Lighthouse, the lighthouses of Bar Harbor and the Acadia region are among the most remote and lesser-known lighthouses of Maine. As the vessel traffic changed in these areas in the early 1900s, some of these lighthouses were sold into private ownership while others became less important as aids to navigation. Since the structures were located on remote islands or in a highly restricted military installation, the photographs and historical firsthand memories of most of these lighthouses have remained elusive and seemingly lost in the dusty pages of time. Through vintage photographs, Lighthouses of Bar Harbor and the Acadia Region uncovers the history of these structures that kept watch over Maine’s rocky coast.
