"Batteries of the Atlantic" refers to a series of coastal fortifications built during the 19th and early 20th centuries along the Atlantic Ocean coastline. These batteries were designed to protect strategic ports and naval bases from potential naval attacks, particularly during times of conflict such as World War I and World War II. Many of these fortifications featured heavy artillery and were strategically placed to cover key maritime routes. Today, some of these sites have been preserved as historical landmarks, offering insights into military history and coastal defense strategies used during their operational periods.
