The patron saint of Ornavasso is Saint Nicholas, celebrated on 6 December in the Church of San Nicolao.
On 8 September, the feast of the Madonna del Boden, or of Miracles, is celebrated: to welcome the growing number of pilgrims, around the mid-17th century the oratory was expanded with the addition of the choir, two chapels and the sacristy. The municipal territory also holds the Sanctuary of the Madonna della Guardia and the Sanctuary of the Madonna di Oropa, as well as the Necropolis of San Bernardo.
