The Cathedral of San Michele
The Cathedral of San Michele opens onto the square of the same name, the heart of the city. The facade, without a definitive renovation, offers a reading of the various modifications made to the building at different times. From the Romanesque church with a single nave, visible in the lower and central part, separated from the bell tower, to a subsequent extension in Gothic style with the addition of the side aisles and the incorporation of the bell tower. It is also clearly visible, due to the lowered frames, the elevation made necessary for the progressive lifting of the floor, a phenomenon that characterizes the whole city as a result of the river supply of the Centa. The descent towards the original level of the cathedral in the XIII century is striking. The Bell Tower, together with the Civic Tower and the Town Hall Tower, has become, as a group of the three Towers, one of the symbols of the city.
