Robert The Bruce’s Cave in Kirkpatrick Fleming, Dumfriesshire, Scotland

This is thought to be the place that inspired a legend. The story goes that Robert The Bruce, King of Scotland way back in the early 14th century, retreated to it after a series of crushing military defeats.
With the hated English well on top, Robert had considered giving in. It was then that he saw a spider repeatedly trying to spin a web over the entrance of the cave, and he realised that perseverance would bring rewards.
So he left the cave, probably breaking the poor spider’s web again on the way out, and began to wage a successful guerrilla war against the English.
Bruce’s Cave (or at least the one with the most plausible claim to being it) is now controlled by a nearby caravan site in Kirkpatrick Fleming, Dumfriesshire, Scotland.
Visitors can enter, although arachnophobes would be well advised to steer clear – spiders still inhabit it.
