HISTORICAL MILESTONES

Iron Mountain has a rich and colorful history dating back to 1951, when a depleted iron ore mine in upstate New York was converted to the nation's first secure underground records storage center, designed to protect corporate vital records in the event of a nuclear holocaust. Since that time, the motivation for records storage and management services has changed, and Iron Mountain has been at the vanguard of this evolving industry.
