The Church of San Filippo Neri and the Immaculate Conception was designed by Francesco Massari between 1680 and 1722 and finished by Lucio Bonomi. The interior, made by masters Mastro Tobia and Lorenzo Vibi, is decorated with gold and stucco. It has a Latin cross plan and a single nave with Corinthian pilasters; the side chapels feature barrel vaults. The main altar dates back to 1843 and houses a statue that replaces a precious painting, probably made by Lazzaro Baldi, upon design by Pietro da Cortona, now placed on the transept. In the transept you can admire paintings by Ubaldo Ricci da Fermo (first half of '700);  in the third chapel on the left is the only marble altar of the church, that houses some relics of San Filippo contained in the polls and in two busts of the Saint; in the second chapel, erected in 1725 by Recco family, is the "Transit of St. Joseph". Since 1996 the crypt has been home to the Museum of Rural Life of the Piceno area.
