Chiesa di San Floriano

The ancient pieve of Arsio is mentioned from 1241, but it was probably built earlier. For a long time it had no autonomy and remained bound to the fortunes of the counts D'Arsio: it probably began as the family's private chapel, without endowments or income, and it is thought that even the baptismal font granted by the diocese fell within those limits of jurisdiction.

From 1512 the old building was almost completely demolished and rebuilt on the same site. In the choir of the church is recorded the name of the man who carried out the rebuilding, Pietro Carlon of San Fedele in the val d'Intelvi, and beside it the date 1512, which applies both to the opening of the building site and to the erection of the bell tower.

A clock was later installed on the tower. In the second half of the 19th century the paving of the hall was renewed, the balustrade separating the presbytery was built and the Chiappani of Trento cast new bells. The church was the parish church of the community until 1966, when it was succeeded by that of Maria Ausiliatrice.
