Mombaroccio
Mombaroccio is a medieval hill-top town which still retains its walls. It was founded through a merger of smaller castles.
It is a quiet town, park in the lot below the walled city and walk in through one of the gates. There are stately houses along the centre street, and a pleasant central plaza. I found the cafe very friendly and helpful - give me Italian lessons on the proper pronunciation of "clocK in Italian."
