The most ancient notable monument of Cuneo is the 13th-century church of S. Francesco, displaying Romanesque-Gothic features and a fine marble portal of 1481. The church of S. Croce preserves its original Gothic structure in part of the choir; the remainder of the building was remodelled in the 18th century by the architect Francesco Gallo, to whom is also owed the reconstruction of the medieval church of S. Ambrogio. In the small sanctuary of the Madonna degli Angeli, built in 1450 but much dilapidated thereafter, only scant remains of 15th-century frescoes survive. At Borgo S. Dalmazzo stands the monasterium S. Dalmatii de Pedona, sive de Burgo S. Dalmatii: a Benedictine abbey founded in the 7th century by King Agilulf and Theodolinda; it belonged first to the diocese of Asti, after 1388 to that of Mondovì, and now to Cuneo (v. Cottineau, I, cols. 440–41).
