Synopsis: From the book: A lighthouse is a tower by the sea with a brilliant light at the top to guide ships through dangerous waters. Lighthouses are usually built on rocky coastlines, isolated reefs, and at the entrances to harbors and estuaries. They have to be tall, so they can be seen during the day, and so that their light can shine for a long distance out to sea at night. As well as guiding ships along the coast to their destinations, they give warning of underwater rocks. Each lighthouse has a distinctive shape or an identifying color that allows mariners to know which lighthouse they are looking at; they can then be sure of their exact location. In some places where fog is common, lighthouses also emit warning sounds to alert boats and ships that they are near danger. This book explores lighthouses and their history. A fascinating book.
