The patron of Cittiglio is Saint Julius, celebrated on 31 January in the Church of San Giulio. The parish also treats 16 July, in honour of Our Lady of Mount Carmel, as a feast day.
At the ancient Romanesque chapel on the hill, the feast of Saint Blaise is celebrated every 3 February, ending with the blessing of the throat and a bonfire; the feast is then repeated on the morning of the first Sunday after 3 February, with the same blessing. The town also holds Villa Ripamonti and the La Cort di Ratt house-museum.
