This church houses one of the richest collections of silverware in the whole of the Chiavenna valley, mainly thanks to gifts by the people who emigrated to Naples and founded a society in 1540. The building assumed its present appearance as the result of sizeable extensions which began in the 1600s (for instance, to raise the bell tower, originally built in 1494) and continued throughout the 1700s (the square at the front was built by Giacomo Martinoia, from Ticino). The baptismal chapel, three confessionals and the organ balcony, all of which have been preserved, are the work of Giovanni Albiolo from Bellagio (17th-18th century).
