Sol and I went on a cycle today. We went to do a 10 miler but then decided to go up the hill at Inchindown to find the 'secret bunkers' in the hillside.
It was a steep climb.
We soon found the first entrance.
I must admit I'm not exactly sure what the purpose of these hillside bunkers was but it was something to do with the tanks in Invergordon. You can read an interesting account of one of them being bombed in WW2 here. The bombing of tank 13.
