Near the Italian town of Foresta in the province of Caserta, and very close to the extinct volcano Roccamonfina, there is an area called Ciampate del Diavolo (literally devil's footprints). It is so named because of a trail of footprints, divided into three sections, clearly visible on the solidified lava of the volcano fossilized thousands of years ago.

The name given by the locals alludes to the belief that only a demon could walk on hot lava to leave such footprints.
