Approaching Ardesio from the valley and crossing the Ludrigno Bridge, a striking view is immediately seen: the beautiful, little church of St. Peter.
The Oratory, constructed on the extreme edge of an ancient river terrace, seems to have come out of a pre-existing Romanesque tribulina. A precise dating appears difficult: probably the construction started in the XIVth century with substantial renovation in the XVth century. The construction of the portico is certainly later than that. It is said to have happened in compliance with the wishes of Carlo Borromeo of the XVIth century.
Inside, the main altar raises one’s interest with the fresco above attributed to “Alessandro de Ardese”. The fresco also recalls the Baptism of Christ. One final particularity: the fresco follows the strong undulations of the walls, which in the remaining part are perfectly flat. This is confirmed by the hypothesis of those who think the fresco belongs to 1400.
