소개
On forested hills surrounding the nation's capital are the remnants of a complex system of Civil War fortifications. These strategic buttresses transformed the young capital into one of the world's most fortified cities. By 1865, 68 forts and 93 batteries armed with over 800 cannons encircled Washington, DC. Today, you can visit 18 of the original sites now managed by the National Park Service.
