Historic forts are military structures built to protect strategic locations and serve as bases for troops. They often feature thick walls, towers, and moats, designed to withstand attacks. Many forts were constructed during significant periods in history, such as the American Revolutionary War or the Civil War, and they played crucial roles in battles and defense strategies. Today, many historic forts are preserved as cultural sites and tourist attractions. They offer visitors a glimpse into the past, showcasing artifacts, architecture, and reenactments. Examples include Fort Sumter in South Carolina and Fort Ticonderoga in New York, both of which highlight important events in American history.
