The church is now in a corner next to the frescoed house of the vicar, entered by a large rounded arch.

Much of the interior was rebuilt in the 15th century, and covered with frescoes in a style influenced by Byzantine iconography.

The chapel to the left, completed later, has a series of frescoed panels Scenes from the Life of The Virgin Mary (1525), masterworks by Lorenzo Lotto.

The latter chapel has a canvas Madonna and child with Saints Peter and Paul by Giovanni Paolo Lolmo.

On the right wall, there is a Madonna of the Rosary and Saints by Enea Salmeggia and in the counterfacade, two frescoes by Antonio Cifrondi depicting Christ and the adulterous woman and the Last Supper.
