Old Base Museum Campus

Nearly 200 years after opening, the Plattsburgh Barracks, which became the longest military operating facility in the US, completed its mission and closed. What began as 200 acres of military-operated land in 1814 evolved to nearly 5,000 acres of undeveloped property full of rich history. Today, three museums and two breweries operate within 500 feet of each other on the former Plattsburgh Air Force Base, each of them doing their part to bring our history back to life!
