Photographs of one hundred lighthouses have been selected for their beauty, clarity of architectural depiction, geographic distribution, and representation of types. Twenty American states are represented: Michigan, 15; Wisconsin, 9; California, 8; Florida, 7; Oregon, North Carolina, and Maine, 5 each; Minnesota, 4; New York, 3; Massachusetts and Ohio, 2 each; and Pennsylvania, Virginia, Alaska, Washington, Illinois, New Jersey, South Carolina, and Rhode Island, 1 each. These group by coast into 33 Great Lakes, 25 Atlantic, and 15 Pacific U.S. lighthouses. Half the U.S. lighthouses shown are conical; a fifth are square; a tenth are octagonal; a tenth are cylindrical; and one example each is hexagonal and nonagonal. Nine extra-U.S. lighthouses are also included for comparison’s sake. Julie Stetzko Taff provides illuminating captions.
