Lighthouses may stand watchfully over serene waters one day and be bombarded by immense waves the next. They may look out on the most spectacular views, mark the entrance to a busy harbour or be placed in some of the world's most desolate locations. To seafarers they are guiding lights in dangerous waters, but, once decommissioned, they can acquire an air of mystery. They are the most strictly functional of all civilian buildings and yet they can be surprisingly beautiful and varied in design. Are they square, cylindrical or octagonal? Are they single structures or towers on top of other buildings? Are they made of wood, stone, brick, or concrete? Are they coloured with stripes or bands? From Lake Michigan to the Arctic Circle, from the British Isles to Brazil, Lighthouses celebrates more than 200 structures and the stunning vistas that surround them. Taking examples from all around the world, the book features an immense array of operating and disused lighthouses from the 18th century to the present day, from those marking ocean coastlines to structures besides lakes and on rivers, from lighthouses cloaked in ice to Art Deco classics to tilting structures abandoned in sand dunes. Presented in a handy pocket-sized format, Lighthouses is arranged geographically, with more than 200 colour photographs and captions explaining the construction, operation and history of each entry.
