Exceptionally rare opportunity to acquire a Cold War–era underground nuclear bunker, originally constructed in the late 1960s as part of AT&T’s Long Lines network and engineered for durability, redundancy, and long-term self-sufficiency. The property features an approximately 4,800+ square foot below-grade reinforced concrete bunker, configured with multiple secured rooms, hardened corridors, and support areas. Several rooms include private bathrooms, and the layout was designed for both manned and unmanned operations. The facility was constructed with mission-critical infrastructure standards and controlled internal access. Approximately 15 years ago, the facility underwent renovations intended to support use as a secure data and communications site, with upgrades to power distribution, mechanical systems, and interior spaces to accommodate sensitive equipment and long-duration operations. Power infrastructure includes commercial electric service with automatic transfer capability and a 150 kVA diesel generator supported by on-site fuel storage designed for extended runtime. Mechanical systems include multiple heat pumps utilizing a closed-loop well water system for heating and cooling, originally engineered to operate continuously and efficiently. Environmental systems incorporate multi-stage air filtration and water purification components, designed for long-duration occupancy. The facility also includes specialized mechanical rooms, utility areas, and hardened support spaces typical of secure infrastructure installations. Situated on approximately 9+ acres in a private rural setting, the property includes an above-grade concrete block service/garage building historically used for equipment staging and operations. The site benefits from controlled access, substantial setbacks, and a low-profile footprint. Suitable for a variety of specialized uses including secure private occupancy, continuity-of-operations, research, storage, or other approved applications. Due to the unique and sensitive nature of the property, certain details are intentionally limited. Showings by appointment only. Proof of funds required.
