Poppi is a small town with little to no tourists. But in saying that it was largely connected to Dante. Especially Castello di Romena and Castello di Poppi. Castello di Romena used to have two different walls. An internal and an external. The external wall contained the warning tower. Which was used in order to warn the castles nearby that they were under attack or to communicate with each other. The people contained within the external wall were allowed to come into the internal circle for protection. In order for those people to get into the internal wall they had to pass through essentially the protection tower. As you walk through this tower and look upwards you can see murder hole. These were used to throw oil and spears down at the enemy in hopes to kill them. Once inside of the internal wall, we have the castle and the prison tower. Dante was actually imprisoned here. He was invited to Castello di Romena to counterfeit Florentine coins. Dante refused to counterfeit the coins and he was imprisoned in this tower. While there he was forced to counterfeit the coins. The prison tower was arranged by levels of crime. The worst being at the bottom. Here, he was inspired to write the inferno with the worst of sins at the bottom. Castello di Poppi is close to where he fought in battle with the Guelfs against the Ghebellines.
