Sant'Ansano. At the intersection of via Brignone, Arco di Druso and Monterone there is a noteworthy architectural complex made up of buildings dating back to various eras and practically superimposed on one another. A first century AD/font> Roman temple can still be seen in via Arco di Druso. It was originally made of a cell and a pronaos, as can be gleaned from the stylobate and the top of a column still remaining.

The Crypt of Saint Isaac dates back to the eleventh or twelfth century. It has a small nave and two aisles with columns previous used elsewhere and a cross vault. Its walls and apse have splayed slits and significant fragments of thirteenth century frescoes. The church as it stands today with a sixteenth century two tiered cloister next to it was completely rebuilt at the end of eighteenth century. Its single nave holds frescoes including one particularly noteworthy by Spagna.
