The small church, dedicated to San Grato, Bishop of Aosta, stands alone on the hill overlooking the lake. It lives on the legend of the hermit brothers of the Lario, being part of the circuit of watchtowers located on the slopes of the mountains overlooking the lake.
The first documented news dates back to 1679, when it was expanded by the architect Giorgio Vitale, a native of Muggiasca, followed by the work to build the altar. In 1692 the sacristy was added, in 1707 the small bell gable was added.
In these rooms, since 2000, there has been an exhibition dedicated to the Resistance in Muggiasca; near the entrance, there is a monument in memory of the Partisans who fought on those mountains.
In 1931, during redecoration of the interior by the painter Paolo Vitali of Bellano, a fresco was found that testifies to the antiquity of the church and that was fully restored in the early nineties.
Today, the oratory houses a copy of the wooden statue of San Grato, dating back to the thirteenth century: the original, a work of great value made in Aosta, is kept with the parish church’s treasure.
