If its what I think it is I wandered up there about 12 years ago and have been meaning to go back. Its the remains of an anti aircraft gun from what I could tell but like I say, a few years have passed since I was there. Drove past last week and looked like something was happening on site as there looked like there were portacabins or something on site but as I was driving I only got a quick look. If you fancy wandering up (I was going to cycle up as you cant park a car) give me a shout.

I had the map of Europe too. I think what's happened was sheepdug zoomed in and then copied the link from the address bar, which doesn't work with Google Maps. If you want to link to a particular map, you need to use the "link" which is part of the "Print, Send, Link" group on the right of the page. That gives a URL that will reproduce the current view.
Yep thats it !!!! merci for all your help in identification... I went up there recently from there other side (clarkston) and its pretty run down but all the buildings etc are intact... i think someone is building somthing close nearby but the round shaped layout got me thinkin it was gun placements etc... cheers for all your digging folks ... oh btw does anyone else get together on this board to go exploring ? if so when and where ?
