The church “Santa Maria in Trivio” was built in Cameraggio, which together with the nucleus of Pianello formed the fraction of Montecoronaro.Of the ancient parish church of the Abbazia di Trivio, demolished because it is decadent, it only preserves the title.
After the earthquake of 1918 it was deeply restored, but it is only after the 2003 earthquake that its structure was made much more solid. On the austere façade stands out a mullioned window and a terracotta lunette, where the Annunciation is depicted.
