Until it was decommissioned in 2000, the former Seneca Army Depot was a major munitions supply base for every military conflict from World War II to the Persian Gulf War. Built in 1941 on more than 10,000 acres, the depot stored bombs in reinforced concrete structures (known as "igloos") with arched sides and semi-circular roofs that still stand to this day. During the Cold War, nuclear weaponry was rumored to be stored on the site - making the depot and the Finger Lakes a prime target for foreign missile attacks.
