RAF Airbase is most secretive place in UK that has completely classified activities

If you were flying over the UK's top secret RAF base in Yorkshire, you'd probably spot it right away.

It has distinctive white domes that look a little like gold balls, and are quite hard to miss.

But the funny little structure is a whole lot more serious than it looks. In fact it's so serious that almost no one knows what actually goes on inside.

You may have driven past RAF Menwith Hill at some point in your life.

It’s hard to miss thanks to its massive white domes - nicknamed ‘golf balls’ for obvious reasons - which are used to shield and protect important radar equipment.

But what is the Yorkshire facility actually for? Little is known about the exact details of its daily operations.

However, previous planning documents submitted to Harrogate Borough Council claimed the site was set up to offer ‘communication intercept and intelligence support’ services to the UK and the US.

Menwith Hill first started in 1954, when the British War Office purchased 246 acres of land at Nessfield Farm near Harrogate, which was later increased to 562 acres.

Access to the land was given to the US Department of Defense (DoD) under the NATO Status of Forces Agreement 1951, providing a key centre for monitoring and intercepting the world’s communications, including countries in Europe.

Construction of the station kicked off in 1956, and today it is considered to be the largest electronic monitoring station in the world, used in majority by the US National Security Agency (NSA).

Although many suggest that the site was set up primarily as a spy hub during the Cold War, the Soviet Union is no more. Which begs the question - what is it being used for today?

Although demolition work took place there in 2019, it remains a significant base for the US and the UK.

According to Yorkshire Live, there were even reports of America investing a whopping $40 million on expanding Menwith Hill’s surveillance capabilities.

Aside from the distinctive radomes, there is also an operations building said to be the size of a football pitch, as well as a huge auditorium for briefings.

The outlet went on to state that up until 2015, there were schools for the children of those who work there, as well as a pool hall, bar, restaurant and shop, bowling alley and run track.

While this all sounds pleasant enough, the military base has sparked controversy over the years, with peace campaigners demanding to know what goes on behind its doors.

The Menwith Hill Accountability Campaign (MHAC) was even set up to bring public awareness and scrutiny to the issue of its presence, and roles of the US visiting forces and their agencies at the site.

Their website states: “MHAC recognises a significant risk to the Yorkshire and wider UK population from the United States surveillance activity at Menwith Hill because it makes a significant military target.”

Whether or not the secrets of Menwith Hill will be brought to light in the near future is yet to be seen, but for now, it’s staying put as the most mysterious landmark in the UK.
