Forts are strong buildings or structures built to protect people and places from attacks. They often have thick walls, towers, and sometimes a moat to keep enemies away. Historically, forts were used by armies to defend important locations, like cities or trade routes. Many forts are found in different parts of the world, showcasing various architectural styles and designs. Today, some forts have been turned into museums or tourist attractions, allowing visitors to learn about history and military life. Famous examples include Fort Sumter in the United States and The Tower of London in England. Exploring these sites can be a fun way to connect with the past!
