The origin of the church of San Martino is uncertain as we are in possession of few historical evidence relating to its original medieval structure, are visible a portal on the north side and two side chapels - now converted into sacristies - in addition to the bell tower that is clear Romanesque plant. Three naves with ceilings decorated with frescoes make up the interior, which houses an organ of great relief, a well-crafted Serassi from 1848, created with the collaboration of the architect Ulisse Salis and the artisan Francesco Bonacossa from Tirano. The organ was subjected to a radical intervention of extraordinary maintenance in 2016, which fully recovered its functionality, aesthetics and structural solidity.
