The parish of Mairengo also included Faido, Osco, Calpiogna and Campello. The church of San Siro was first mentioned in 1171 and in the 16th century it was expanded and renovated. It was the most important church in the central Levantine. The current building was restored in 2001, but still bears traces of the old romanesque church facade.

The local economy was based on livestock, which had virtually disappeared at the end of the 20th century, although the alpine pasture of Alp Formazzora in the Bedretto valley was still cultivated. The village section of Polmengo is home to a large construction site for the new Gotthard Base Tunnel.[2]
