Orvieto, Italy

The Italian hill town Orvieto is settled on top of Volcanic rocks, housing this mysterious ancient underground city. Nowadays, it’s famous for its white wines. But the city belonged to the ancient Etruscans, who excavated down to carve cisterns and wells initially.

How did it come to be? Gradually, it developed into an underground maze of tunnels, counting up to 1,200 galleries and tunnels.

While it was mainly used to hold wines, it also showed remains of the Etruscans and medieval oil presses when discovered. During World War II, the underground tunnels of this village were also used as bomb shelters.
