Occupying the western shore of one of the most scenic bends in the Hudson River, the academy consists of some 16,000 acres of training grounds, playing fields, and buildings constructed of native granite in the Military Gothic style. The oldest continually garrisoned post in the U.S. Army, the citadel was founded in 1778 and opened as a military academy in 1802. Distinguished graduates include Robert E. Lee, Ulysses S. Grant, and Douglas MacArthur. The world's oldest and largest military museum, the West Point Museum in Olmstead Hall, showcases a vast collection of uniforms, weapons, flags, American military art, and other memorabilia. Fort Putnam, built in 1778 and a key component of West Point's defense during the Revolutionary War, was restored in the 1970s. Campus visits are by bus tour only (bring photo ID), but you do get a chance to step off the bus, look at a few memorials and cannons up close, and perhaps glimpse cadets in action. Civilians are also allowed on campus for sporting and cultural events, including football games, theater presentations, parades, and concerts. You can visit the museum and visitor center without taking the $11 tour. Tours aren't given during graduation week (usually late May) and on Saturdays of home football games.
