Located on the Lazio side of the National Park of Abruzzo, Lazio and Molise, closer to the border with Abruzzo, there is the small and pretty town of Campoli Appennino, overlooking an impressive karst basin, known as Tomolo, where houses are developed along a loop on the edge of the basin, a feature that makes it quite unique in Lazio region; at the back of the town of Campoli – whose name comes from the Latin campora, the land cultivated on the mountain – stands Italian central-south Apennines.

Even though the information about the origin of the town is not certain, being traditionally dated back to the time of Count Gandolfo of Sora and Aquino, after the Longobard destruction of the 7th century, Campoli shows a clear medieval structure in its tower, in the walls and in the picturesque streets of the town centre. conte Gandolfo di Sora e Aquino dopo la distruzione longobarda del VII secolo – Campoli presenta una chiara struttura medievale nella torre, nella cinta muraria e negli spazi caratteristici del centro.

You can start your walk right from the medieval tower, the symbol of the town and its oldest building: built by the Lombards, the tower was later owned by the dukes Cantelmo from Alvito in the 14th century, who are represented in bas-relief of the coat of arms depicting the family symbol of the rampant lion, which can be seen on the south facade of the tower; used in the last century as a water tank, today the tower is a place of cultural interest accessible through guided tours.

Walking away from the tower and along the walls of the town hall, a maze of small alleys guides you to the discovery of the old buildings and the views from the walls, towards Porta Suso to enjoy the view opening onto the west; from there you can walk back to Piazza Umberto I, crossing Via Campo dei Fiori with its portals and characteristic spots.

At short walk from the square there is the Church of Saint Andrew the Apostle, with its baroque lines on a medieval architecture: inside, besides the altar and the artistic works, you can awe in gaze at the characteristic Venetian-style mosaic floor made of the "gravel of Campoli" (breccia di Campoli), dating back to 1881, and the chapel dedicated to the Holy Family where to contemplate the 19th-century canvas, from an unknown author, in which San Felice the martyr is portrayed in the act of donating the town to God, a picture showing us how Campoli Apennines was at the time.
