Small 13th-century alpine church outside the village of Monteaperta, of Romanesque origin with several reconstructions and fragments of four layers of frescoes from different periods. The layer attributed to Gian Paolo Thanner is quite readable.
The church is equipped with a rare hagioscope that allows the mass to be heard from outside. In the sanctuary of Santissima Trinità of Monteaperta, the communities of the Cornappo and Torre valleys meet every year in June to renew the solemn and evocative rite of the Kiss of the Crosses.
