From storm-battered coastlines to rocky islands far from shore, tall towers have stood for centuries, sending out beams of light to guide sailors through the darkest nights. These towers aren't just stone and glass-they are symbols of courage, guardians of the seas, and lifesavers for countless ships. This book takes young readers on an exciting journey through the world of lighthouses, revealing how they were built, how their lights worked, and why they were so important to sailors throughout history. Kids will learn about ancient fires set on hilltops, the invention of the Fresnel lens that changed everything, and the brave keepers who spent their lives making sure the lights never went out. Real stories of shipwrecks, rescues, and famous towers bring the history alive, while modern technology like electricity, solar power, and GPS shows how lighthouses still play a role today. Written in a fun and engaging style for ages 7 to 12, this book balances fascinating facts with gripping tales that will spark curiosity. It's a chance to step inside the lantern room, hear the echo of footsteps on spiral staircases, and discover why these lights by the sea continue to capture the imagination even in the digital age.
