The Church of the Santi Martiri with its one nave and four side chapels was built at the end of the 16th Century. Del Vacca, with decorations representing the Sacred Heart of Jesus and the Sacred Heart of Mary, encloses the vaults in two large oval medallions. With a high altar designed by Juvarra, it has a black marble pediment holding an urn containing the relics of the Saints. In the interior walls two niches contain statues of St. Goslino and St. Juliana.
