Lighthouses are increasingly endangered by modernization and abandonment. Simple steel skeletons are replacing the picturesque, conical towers, squat screwpiles and Cape Cod styles so much a part of America's maritime history. This traveler's guide to more than 300 of the nation's most significant lighthouses and lightships includes an introductory look at the evolution of lighthouse technology and how these obsolete but beloved structures can be rescued.
