Penna is an ancient hill top town. It is covered in mud for most of the year due to heavy rain. There are half a dozen churches and a tiny early 19th century theatre. At the very top of the town are the remains of the ancient fort with a panoramic view up to the mountains and looking out at the surrounding hilltop towns. In the summer the municipality organizes events on numerous evenings, including the Festa della Polenta and Otto Giorni Di Un Linguaggio Volgare, which is enjoyed by tourists.
