Tarr Steps is the name given to a stone bridge that crosses the River Barle on Exmoor.
The bridge dates to at least medieval times, and according to legend was built by the Devil himself, for his own use. He carried the stones there in his apron, and completed the bridge in a single night.
He swore no one else would cross it, and when the local people sent a cat across, it was torn to pieces. But the local parson then stepped onto the bridge, and the Devil met him halfway, saying,
“You’re a black crow.”
To which the priest replied:
“I’m no blacker than the devil.”
The two then traded insults of such ferocity that the trees around them wilted; but in the end the Devil beat a retreat, and ever since the bridge has been safe to use.
