Oratorio della Madonna del Restello
Right at the beginning of the town of Castiglione, with the green Intelvi valley as a back ground, stands the oratory of the Madonna del Restello built in the 17th century to thank the Madonna for the end of a plague that had infested the valley. Inside the precious baroque stuccos of the altar and the "scagliola" frontal, show the craftsmanship of the local artists. The Maestri Intelvesi, a group of architects and artists, worked in the courts of Europe but during the winter returned to their valley embellished it with their works of art. Worthwhile are also the frescos of Giulio Quaglio.
