Noteworthy is the parish church dedicated to St. Martian, in classical Renaissance style, with a single nave and neoclassical chancel and choir.
It stands on Piazza del Castello; was founded in the 13th century and then enlarged between 1758 and 1763 and, finally, restored in 1843.
The interior paintings date mainly from the 19th century and are attributed to the school of Lorenzo Ivaldi, active in Piedmont at that time.
It stands in a panoramic position.
