The first records of the church of Saint Apollinaris in Vaglio date back to the 13th century, when it depended on the parish of Renno, like most of the churches in the central Scoltenna valley.
The parish priest Don Leonardo Rossi began the reconstruction of the church in 1629: the expenses were covered by the communities of Vaglio and Valdalbero, united in a single parish.
Two beautiful paintings dating back to the 17th century depict the Madonna of the Rosary and the Annunciation, and were originally the altarpieces adorning these altars.
The notoriously subsidence-prone terrain of this valley meant that the church, at risk of collapse, had to be rebuilt two centuries later. The project was begun in 1862 by Don Domenico Martelli, but actual building work only started in 1874, and he was to die just three years later. His successor, Don Giuseppe Mordini, completed the project in 1882.
The great landslide of 1901 swept away a large part of the village, destroying the new church and sparing only a chapel in the nearby cemetery, the Carlotti chapel; this still exists today and, at the time, served as a temporary church, pending the construction of a temporary wooden hut.
Art treasures from the old church were temporarily housed in a barn, but were lost following an arson attack. Twenty-six years went by, and nothing was done about the reconstruction of the church until the arrival of the new parish priest, Don Sanzio Barbieri, in 1927. The following year, he laid the foundation stone of the present church, and building work was completed in 1935. However, due to the war in Ethiopia, the war in Spain, the Second World War and the difficult post-war period, the church of Saint Apollinaris in Vaglio was not inaugurated until 1956.
The bell tower, dating from 1987, houses a set of four bells from the De Poli foundry in Vittorio Veneto.
