When waves higher than the vessels that sail upon them smash against the half-submerged rocks at the extremities our coastline, the whole ocean becomes a raging foam which continues to claim the lives of unwary navigators. Man's struggle to build a permanent and durable structure such as a lighthouse on these sites is a story that cannot fail to stir the emotions of anyone who enjoys tales of endeavour, ingenuity and dogged determination. In this second edition of his book, Christopher Nicholson vividly describes the construction and history to the present day of some of the world's most famous lighthouses. Book jacket.

Lighthouses are striking totems of our relationship to the sea. For many, they encapsulate a romantic vision of solitary homes amongst the waves, but their original purpose was much more utilitarian than that. Today we still depend upon their guiding lights for the safe passage of ships. Nowhere is this truer than in the rock lighthouses of Great Britain and Ireland which form a ring of twenty towers built between 1811 and 1904, so-called because they were constructed on desolate rock formations in the middle of the sea, and made of granite to withstand the power of its waves. Seashaken Housesis a lyrical exploration of these singular towers, the people who risked their lives building and rebuilding them, those that inhabited their circular rooms, and the ways in which we value emblems of our history in a changing world.

Lighthouses have always unsettled and attracted in equal measure, highlighting the triumphs and failures in humanity's battle with the forces of nature. Taking as its heroes the lighthouses themselves, Sentinels of the Sea describes the engineering genius that allowed their construction on even the smallest of rock outcrops and the innovations that made the lights so powerful and reliable. Intricate, elegant architectural plans and elevations, and evocative period drawings and photographs showcase the innovative designs and technologies behind fifty historic lighthouses built around the world from the 17th to the 20th century. R.G. Grant's engaging and authoritative text chronicles the incredible feats of engineering and endurance that brought these iconic, isolated towers into being, the advances in lens technology that made the lights so effective, and the everyday routines of the lighthouse keepers and the heroic rescues that some performed. Packed with extraordinary stories of human endeavour, desperate shipwrecks, builders defying the elements and heroic sea rescues, the book also reveals the isolation and vulnerability of the dedicated lighthouse keepers.

Christopher Nicholson vividly describes the construction and history to the present day of some of the world's most famous lighthouses in this classic book which has become the standard work on the subject. It brings the story of the rock lighthouse completely up-to-date--from the day the first granite block was laid, through construction, automation, the disappearance of the lighthouse keeper, right up to the technology of today with the use of solar and wind power. This is a joy to read with its mix of exciting text, some of the most dramatic new colour photographs of British lighthouses ever taken, a selection of beautiful, hand-coloured plans and drawings, a brand new chapter about Rockall, the most unusual rock 'lighthouse' of all, and a detailed appendix. For those not intimately connected with the sea it's almost impossible to imagine waves higher than the vessels that sail upon them smashing against half-submerged reefs that stir the whole ocean into a raging foam of white water. Man's struggle to build a permanent and durable structure such as a lighthouse on these sites is a story that cannot fail to stir the emotions of anyone who enjoys tales of endeavour, ingenuity and dogged determination.

The sheer beauty of the elegant, lonely lighthouses along our shores--and their unspoiled, scenic natural settings--has captivated our collective imagination. A celebration of one of America's purest landmarks, The Ultimate Book of Lighthouses is a must-have for any home.

For centuries the seas around Scotland were notorious for shipwrecks. Mariners' only aids were skill, luck, and single coal-fire light on the east coast, which was usually extinguished by rain. In 1786 the Northern Lighthouse Trust was established, with Robert Stevenson appointed as chief engineer a few years later. In this engrossing book, Bella Bathhurst reveals that the Stevensons not only supervised the construction of the lighthouses under often desperate conditions but also perfected a design of precisely chiseled interlocking granite blocks that would withstand the enormous waves that batter these stone pillars. The same Stevensons also developed the lamps and lenses of the lights themselves, which "sent a gleam across the wave" and prevented countless ships from being lost at sea. While it is the writing of Robert Louis Stevenson that brought fame to the family name, this mesmerizing account shows how his extraordinary ancestors changed the shape of the Scotland coast against incredible odds and with remarkable technical ingenuity.
