The parish church of St Martin, in neo-Gothic style with three naves, dates back to 1868. The construction materials were obtained locally and transported free of charge by the inhabitants. The most recent significant restoration work took place in 2002-2003 with the rebuilding of the roof and painting of the exterior. Inside, the museum of sacred art and the enormous crucifix hanging from the vault, probably dating back to the 14th century, are noteworthy.

Within the boundaries of Torgnon there are 19 chapels and numerous oratories. Many of these are from the second half of the eighteenth century, others are older. They bear witness to a spirit of sacrifice, great faith in God and devotion to the Madonna and Saints.
