Scotland has countless unsolved mysteries that have left experts stumped for generations, but one of the most interesting — and least well known — is that of Torwood Blue Pool.
It is a manmade brick pool located in a clearing in the Tor Wood Forest, just outside of Falkirk. The forest was supposedly visited by iconic Scots such as Sir William Wallace and Robert the Bruce.
However, it is Torwood Blue Pool that has remained perhaps the woods' most intriguing feature. The origin of the pool remains a mystery, one that local man Nigel C Turnbull devoted much of his later life to solving.
