Camp it up
While in Comrie, we also visited Cultybraggan Camp, the most complete remaining POW camp in the UK (according to this source). It was built in 1939 and covers 8 acres in a remote spot of Perthshire countryside, containing over 100 Nissen huts in varying states of repair.
The whole site has been bought by Comrie Development Trust, who are in the process of turning it into a community resource. It's a large site and the area towards the back is now hired out to businesses and used for allotments. The enormous firing range that sits behind them is kind of incongruous, but it's great to see the land being put to good use.
Quite a few of the huts have been renewed and repaired ready for tenants.
Other are left exactly as they were when the MoD left - mattresses on the floor, forgotten furniture, tattered posters and remnants of military life.
They do scrub up nicely. This hut (close to a ginormous nuclear bunker, just in case) is now someone's office.
The site is open from morning until dusk so anyone can go in and have a look around. I'm still reading up on it all hence the lack of background in this post, but there's some good info on Secret Scotland. More photos on Flickr.
