Parish Church of San Martino all'Oppio

It is the most valuable monument in the country. Founded around the century X, the current structure dates back to the second half of the 16th century, an example of a late Renaissance building. Restored in the years 1933-40, it has three naves divided by seven sixth-floor arches on each side supported by monolithic columns of Tuscan order.
The airy central nave is covered by a trussed roof: the side aisles have cross vaults. The floor is in sandstone slabs. The number of paintings on canvas from the 1600s and 1700s is conspicuous.
