"Underwater Lighthouses" unveils the captivating history and engineering of submerged and semi-submerged lighthouses, crucial navigational aids in treacherous marine environments. These remarkable sea structures, often overlooked, played a vital role in reducing shipwrecks and saving countless lives. The book explores how the design and construction of these specialized lighthouses represent human adaptation and resilience, dynamic responses to specific geographical and environmental challenges. Discover the ingenuity required to build these structures where the sea meets the sky.

The book progresses by first introducing the different types of underwater lighthouses, such as screw-pile and caisson lighthouses, and then tracing their historical evolution from rudimentary designs to sophisticated engineering marvels. It delves into the innovative construction techniques developed to overcome the challenges of building in marine environments, further presenting case studies of specific lighthouses, highlighting their histories and contributions to maritime safety.

The book's unique value lies in its specific focus on submerged structures, offering a detailed exploration often absent in general lighthouse histories.
