Ssshhh, you know who!

Travelling to Cheltenham everyday, on the upper deck of a bus, you get a good view of things that you don't normally see.
This is GCHQ, The Doughnut, often featured on the news and discussions about national security. It got it's nickname from the building shape which is round with a hole in it!

I don't think I'll be arrested for taking this photograph, it's well signposted around this area and is very clear on Google Earth .

However, just to ensure we do not compromise national security after you read this please shred yourself.
