Little remains of the 5th-century church that was originally built here atop a well sacred to Juno. But that shouldn’t detract from what is a very pretty church, complete with Romanesque bell tower and a 12th-century columned portico.
Inside, the otherwise standard baroque decor is elevated by Guido Reni’s Crocifisso (Crucifixion) above the main altar, and a fine bust by Bernini in the Cappella dell'Annunziata. The French painter Nicholas Poussin, who died in 1655, is buried in the church.
