A Virginia dairy farm that used to hold Army spies is now a winery

Fauquier County, Virginia, might not be the place you think of when you imagine covert ops training, but that's exactly what's happened at an isolated farmhouse and working dairy.

In use since 1803, "Vint Hill," as it was initially known, had several owners before the Army purchased it in 1942 – just in time to train a group of service members in the fine art of espionage. Reframed and repurposed throughout the years, Vint Hill has served as one of the most essential intel-gathering sites you've probably never heard of.

History

Vint Hill is situated near the Signal Intelligence Service headquarters in Arlington but was far away enough from the city that its location and its purpose remained a secret. It was here that the Army housed its Monitoring Station No. 1, a covert spy base.

Established by the Army's Signal Intelligence Service, the 701-acre farm was built in part because the Army needed a secure location near the SIS and a cryptography school.

The geography of Vint Hill was key in the Army's decision to train there. Not only did it boast a quiet countryside vibe where trainees could really get into their coursework, but it also provided "quiet electromagnetic geology," which made it the perfect place for intercepting radio signals. During WWII, that's exactly what service members stationed at Vint Hill did.

Perhaps the most famous is the interception of a message from a Japanese ambassador to Germany. That message, sent in 1943, described German fortifications, contingency plans, and troop strength information.

Once the message was decoded, the information was instrumental in planning the D-Day invasion of June 6, 1944.

The NSA recently released documents that further detail the influence that Vint Hill had on WWII planning. It was a crucial intelligence-gathering station throughout all of WWII and beyond.

After WWII

After WWII, Vint Hill became the first field station of the Army Security Agency, an arm of the NSA. The facility conducted signals intelligence operations.

Declassified Army intelligence lists Vint Hill as one of the largest intercept facilities in the world.

Not only did it serve as an intercept facility, but Vint Hill was also a signal school, signal training center, and a refitting station for selected signal units returning from or heading to deployments.

During and following the Korean War, the station's footprint was expanded significantly, making it a major intelligence hub during the Cold War. Vint Hill personnel intercepted key Soviet diplomatic and military communication sent over teleprints that helped form and shape America's military posture.

In 1961, the Army Electronic Material Readiness Activity moved to Vint Hill and took over the management of signals intelligence and electronic warfare maintenance for the Army Security Agency.

By 1973 however, Vint Hill's mission had changed to research. Its main goal was to aid and assist in the development and support of intel and electronic warfare info gathering for the Army, DoD, and our partner allies. The EPA took over operations of Vint Hill's photographic interpretation center from the DIA, and Vint Hill was renamed as the Environmental Photographic Interpretation Center.

However, that didn't last long. By the late 1979s, Vint Hill was on the list of installations to be closed, and all projects on site were halted. A change in policy in 1981 reversed that decision, and Vint Hill remained open.

Serving as the "giant ear" of the NSA was the core focus of Vint Hill in the early 1980s and eventually became a development and testing site for signal equipment for the CIA and FBI. IN 1993, Vint Hill was once again on the chopping block. This time, the closure stuck. Most personnel were reassigned to Fort Monmouth and Fort Belvoir.

Vint Hill closed officially on September 30, 1997. Now, the site hosts several engineering and tech companies, including the FAAs Air Traffic Control System Command Center. There's a Cold War museum open on-site, but most notably, the former intel-gathering installation is home to the Vint Hill Craft Winery and the Old Bust Head Brewery. There's even a dance school and a gymnastics school run on the property. Talk about reinvention after time in service.
