EVER since the 1950s, the US government’s Area 51 – located deep within the remote Nevada desert – has been the subject of intense conspiracy theories.
But now Google Maps has offered a rare glimpse of the mysterious government site – revealing a massive build up of infrastructure at the base over the past 30 years.
Satellite imagery recorded annually since 1984 shows a rapid expansion of buildings and runways at the base.
This includes the construction of a second runway and what appears to be an extension of the first.
Buildings are also being constructed into the side of a nearby mountain – though what they contain remains a mystery.
