Roca Pedelocco is an archaeological site located at the top of Mount Loco that dominates the city and Lake Pedelocco. It consists of a palace built by the Brancalione lords on the ruins of a previous fortress dating back to the early years of the millennium. There is also Rocca Fort, which was built between 1364 and 1368 by the will of the papal legate Cardinal Albornoz to reassert the authority and power of the Church.
