The Lyons Underground Bunker at 1650 Hwy 51 in Lyons, Nebraska, represents a rare opportunity to acquire a deeply engineered Cold War–era underground facility originally built in 1966 for autonomous, long-duration operations. Designed with self-sufficiency at its core, the structure was constructed with walls up to two feet thick, a 329-foot communication tower, and infrastructure intended to withstand external disasters. Today, much of the original equipment has been removed, leaving behind a clean, well-maintained interior ideal for adaptive reuse. Formerly a communications center, the property retains elements of its historical data infrastructure while providing extensive ventilation, filtration, and mechanical systems that supported continuous, conditioned fresh air delivery. Additional features include a 10,000-pound hoist, a decontamination shower area, a 750-kW turbine generator with capacity to add two additional generators, and robust power service scalable from 1MW to up to 7MW. Situated on more than 24 acres with A-1 Agricultural and C-1 Commercial zoning (special use permit), the site offers flexibility for future redevelopment, secure storage, specialized operations, or mission-critical uses. The facility spans approximately 54,000 square feet across two primary levels with additional mezzanine areas, along with a separate 1,200-square-foot garage. Multiple wells, septic, standpipe fire protection, and detailed building plans included in due diligence further strengthen the property’s readiness for repurposing. With exceptional construction quality, proven resilience, and a unique historical pedigree, this asset stands out as a compelling option for buyers seeking security, scalability, and infrastructure not found in typical commercial properties.
