Chiesa dei Santi Pietro e Paolo Bollengo

In the different phases of building and restoration of the church, what have been identified as salvaged materials such as some decorative elements and Roman bricks, that d'Andrade had sent from Ivrea, were observed. These types of material, together with the irregular masonry made up mostly of river pebbles, and a few bricks laid in a herringbone pattern, suggest a revival of the Lombard architectural model, understood not as Lombardy but as the Kingdom of the Lombards.
