Yes, you read it right.  Pitigliano is a town that dates back to the Etruscan times in Tuscany and the ancestors of the people there had the intelligence of cutting into the soft volcanic tufa rock to establish their dwellings.  They even created channels by cutting into the tufa rock in depths that vary between 3.3 and 33 feet, apparently for water.

In such an amazing historic town, I learnt that it has something in common with Venice.

Do you want to take a wild guess at it?
