Tradition dates the foundation of the monastery to the 10th century, but the canons of Sant’Egidio are mentioned for the first time in 1050. It is the seat of the parish, which includes structures built between the 11th and 18th centuries. The main building, in exposed stone, and the adjacent main bell tower were built in 1512 by the Provost Carlo di Challant.
The present parish of Sant’Egidio was built in 1775 on the site of the previous Romanesque church, of which a simple bell tower is still preserved. On that occasion Count Francesco Ottavio di Challant allowed the chapel of Saints George and Maurice, built in 1407 by the knight Ibleto di Challant as a family sepulchral chapel, to be added to the existing church. The structures of this chapel are still clearly identifiable today, from the outside for the magnificent three-mullioned window in carved stone that stands out on the wall facing the village, from the inside for the Gothic ribbed vaults that were spared by the 18th century interventions.
