The facade was later renovated in modern times with a window and door in neo-Gothic style. The interior, marked by two 15th-century Gothic arches, is a single nave that narrows, at the height of the bell tower, into a rectangular choir. Here stands the main altar and the beautiful 16th-century altarpiece depicting the Virgin with Child and Saints Nicholas and Anthony Abbott; a second altar, erected in the 18th century in honor of Saint Francis, is placed against the southern wall and holds an altarpiece representing Saint Francis in the act of receiving the stigmata.
Along the northern wall, a small lateral entrance, dating from the Romanesque period, led to the adjacent small cemetery. The roof of the nave features exposed trusses, while the choir is covered by a double ribbed vault with Gothic sails. Finally, the interior walls retain painted panels executed respectively around the end of the 13th century (a fragment of the Last Supper on the northern wall) and in 1322, as noted near the figure of Saint Michael at the beginning of the northern wall, at the top. The 14th-century panels depict along the northern wall from west to east: The Flight of the Virgin of Mercy and a part of the cloak; Saints Michael and John the Evangelist; Saint Martin and the beggar; Saints Stephen, Saint Zeno, and Bartholomew; Saint Zeno; Saint Anne, the Virgin, and James the Greater.
On the southern wall, after the restorations of 1998, became visible again, from east to west: The archangels Michael and Gabriel and Saint Bartholomew; Saint Lucy. Finally, on the semi-pendant of the second arch, a panel from the end of the 15th century or early 16th century features the images of the Virgin enthroned with Child among Saints Catherine of Alexandria and Lawrence.
