A brief history of Grotte di Castro
The area was already inhabited in Etruscan times. When the Lombards invaded, the inhabitants took refuge in caves dug into the tuff stone underground. In the 8th century, Charlemagne gifted the town to the Church. From 1537, for an entire century, it was in the hands of the Farnese family. After that the church took over again.
