In the hamlet of Boleto, a visit to the Church of the Madonna del Sasso, which rises on a granite spur projecting on Lake Orta at 638 mt of altitude, is essential.

From the square in front of the church, called "Cusio balcony", you can enjoy breathtaking views over almost the entire lake, the Mottarone, the Alps and the plain towards Novara.

The sacred complex consists of the church, the bell tower and the parish house.
