Four hundred earthen columns, each topped by a boulder, rise on the southern slope of the lower Val Maira. They are the “Ciciu” del Villar (puppets in the local dialect), natural formations of great geological and landscape interest.

The Chiesa di San Costanzo al Monte houses a splendid, ancient building in Romanesque-Gothic style with a crypt inside. Another peculiarity is that it is a rare example of a church with two overlapping storeys.

Magnificently frescoed by the painter Pietro da Saluzzo in the fifteenth century, it is the church of the ancient Benedictine abbey founded in the seventh century. The cappella di san Giorgio, commissioned around 1467 by the abbot Giorgio Costanza di Costigliole, and the 11th century crypt, with cross vault and colonnade, are in good condition. In the chapel, from 1467 to 1469, drawing inspiration from the Golden Legend, Pietro da Saluzzo painted the episodes of the life and martyrdom of Saint George, some of which today are showing signs of damage.
