Valnerina

Valnerina (English: The Valley of That River) is a location featured in Assassin's Creed: Brotherhood. The valley hosts a small city, where Leonardo da Vinci's war machine, the new and improved Flying Machine (now equipped with a cannon), was being mass-produced by Cesare Borgia's army. Once arriving at the location, Ezio interrogated the enginner and got the location of the machine as well as the plans. After stealthily sneaking his way up to the fortress near the city, Ezio Auditore used the first and the only working Bomber to destroy the factories making the machines, and also chariots with suplies. Once all enemies have been defeated, Ezio crashed into a tower, destroying the machine.
