All the interior walls of the church of St Peter and St Paul, erected in 1729 and adjoining a chapel dating from 1550, are covered with frescoes representing religious scenes created by the Abbot Abbot in the 1920s. Sequential lighting accompanied by a commentary makes it possible to discover the richness of this veritable illustrated encyclopaedia of religious and popular history.
