When I was at Cockburnspath Tower I spotted an air raid shelter in the undergrowth. The iron work looked WWII with the wide corrugations typical of this time. The bricks were intact so I wasn't able to see the maker.
There are still metal hinge pintels in the brickwork.
They would have had little warning of fighter bombers coming in from the sea and there are few places to hide when you're ploughing a field.
There are two internal walls in the shelter which makes it look like a toilet, which might have been its other purpose. A toilet could have been useful if you were hiding in there whilst a Heinkel was dropping its load.
Seventy years of weather is beginning to show.
Fields wouldn't have been a normal target for bombers but Cockburnspath sits at a natural choke point above a tight valley with the main road and rail line from Edinburgh to London in the valley.
An unexpected find and good to get some local info, even if it turns out to be nonsense.
