Church of Immacolata Concezione, known as San Filippo Neri, built by the Fathers of the Congregation of the Oratory in the years 1680-1722 to a design by the Roman architect Francesco Massari, a pupil and collaborator of Borromini; when the designer died in 1705, the work was entrusted to the Ripan Luzio Bonomi.
The exterior was consolidated and restored in the year 2000.
The interior, the most beautiful in the city, restored in 1972-74, has a single nave with three chapels on each side, well-pronounced transept, nimble dome in the transept, straight apse; the barrel vault with lunettes, was completed in 1706; stucco decoration began in 1721 by M. Tobia of Milan. Tobia, who made the cornice of the apse and dome; the following year the Filipino layman Lorenzo Vibi of Perugia, performed the stuccoes of the chapels, cornices, and capitals free of charge. M.° A. Costantini of Offida made the stuccoes of the dome and the Filipino symbol repeated in the four pendentives. From 1955 on the walls are the 14 Stations of the Cross, bas-reliefs in scagliola, the work and gift of Uno Gera. Above the arches of the chapels are six canvases depicting (from right): Saint of the Society of Jesus (St. Francis Xavier), St. Sebastian (copy of Guido Reni's work of the same name), St. Gregory the Great (by Lorenzo Foschi, dated 1634); left (from the first chapel): Saint of the Society of Jesus (St. Ignatius), St. Charles Borromeo, St. Andrew the Apostle (work by Lorenzo Foschi and Silverio Carena or Catena, dated 1634).

First chapel on right: Erected at the expense of Fr. Angelo Tognani and the congregation, it is dedicated to St. Francis of Paola, whose effigy is in the altarpiece, probably the work of Ubaldo Ricci of Fermo (first half of the 1700s).

Second chapel on the right: Under the patronage of the Tognani family, it is dedicated to St. Gaetano di Thiene portrayed in the altarpiece, the work of Ricci himself, who is also the author of the other canvases that adorn the chapel: on the right St. John the Evangelist, on the left the Baptism of Jesus, in the cymatium the Magdalene, above in the side ovals. St. Francis Borgia and St. Francis de Sales (right and left respectively); very beautiful are the stuccoes. Under the altar mensa are the remains of Saint Martyr Aurelia Procope, contained in a body executed in plastic by Emidio Paci of Ascoli Piceno.

Third chapel on the right: The altar was made around the years 1855-56: the faux marbles in scagliola were executed by the young Ripan Vincenzo Jezzi; the two iron cornucopes with ornate foliage and birds were worked by Federico Cellini, son of the forger Gaetano; the altarpiece, the Madonna known as the Madonna of the People, is a copy made by Stefano Ciannavei, of an original kept in the bishop's seminary; the frame is valuable work by Vincenzo Salomoni (sec. XIX); the gilding was executed by Emidio Cibatti. Above the door that gives access to the sacristy, canvas (formerly in the first chapel on the left) with Saints Ignatius of Loyola and Francis Xavier (17th cent.): to the right of the door, plaque with bronze medallion (the work of Loredana Luzi) and epigraph (text by Don Antonio Capriotti), placed in 1990 in memory of Msgr. Vincenzo Radicioni, bishop of Ripatransone and Montalto Marche; on the left, canvas depicting the Virgin who protects the church of S. Filippo and the neighborhood of Agello, work (2001) by Ripano artist Mario Vespasiani.

The right chapel of the transept (transept) is dedicated to St. Anne. The monumental altar was erected by the Benvignati-Ricci family; the altarpiece is by Roman Odoardo Vicinelli (sec. 18th century), a pupil of Maratta: it depicts the Transit of St. Anne, lying on her bed, surrounded by St. Joachim (with an open book), the Madonna presenting the Child Jesus to her, St. Joseph, and the kneeling Magdalene; on the right wall, canvas depicting St. Philip celebrating Mass (unknown author from the Baroque period); on the left wall, the Crucifixion, high relief (1969) by Uno Gera: the grandiose work can be called the story of salvation in synthesis.

High Chapel Apse: The neoclassical-style altar was erected in 1843, designed by the Bolognese Gaetano Ferri, who with the help of some disciples decorated the entire apse in chiaroscuro and gold, painted the Eternal Father on the vault and the perspective of the background, which simulates the continuation of the Church; the angels at the top are the work of Domenico Paci; the statue of the Immaculate placed in the niche is a work in scagliola by Fedele Bianchini of Macerata, a disciple of Canova; the figure of the Virgin painted on the sliding curtain that closes the niche, is an early (first half of the 20th century) work by Ida Consorti Capriotti of Ripa; also by Bianchini are the three bas-reliefs below, reproducing (from left) the prophets Isaiah and David and King Solomon; on the walls, two canvases with facts from the life of St. Philip, works by Francesco Ercolani of Macerata.

The left chapel of the transept (transept) is dedicated to St. Philip Neri. The monumental gilded wooden altar was erected by Fr. Giacinto Fedeli; the altarpiece is the work (first half of the 1700s) of Ubaldo Ricci: it depicts St. Philip in sacred vestments, in prayer-contemplation of the Virgin who appears to him holding the Child (classical iconography); on the left wall, canvas depicting the Immaculate Conception, attributed to Lazzaro Baldi of Pistoia (c. 1624. - Rome, 1703) and executed on a cartoon by Pietro da Cortona, restored in 1999; on the right wall, Nativity, high relief (1966) by Uno Gera: heavens and earth, angels and men flock around the infant Jesus man-God, to adore him.

Third chapel on the left: The polychrome marble altar (the only one in the church), executed by Andrea Ascani of Sant'lppolito (Pesaro-Urbino), Keeps relics and relics of St. Philip in a special niche, preserved partly in urns, partly inside two busts of the saint.
After Rome, Ripatransone is the city that has the largest number of authentic relics of St. Philip, thanks to this of Fr. Alexander and Fr. Germanico Fedeli, who were among the saint's first disciples and collaborators. The pictorial decoration door closing the niche, is attributable to Ubaldo Ricci. On the side walls are portraits of Filippini Fr. Alessandro (died 1596) on the left, and Fr. Giacinto Fedeli (died 1727) on the right; the short epigraphs in Latin were dictated in 1858 by Fr. Luigi Michettoni, a Filipino of the Ripana Congregation. The chapel was restored in 1999.

Second chapel on the left: It was erected in honor of St. Joseph in 1725 by the Recco family. The altarpiece, depicting with perhaps exaggerated realism, the Transit of St. Joseph, has recently been attributed to Vicinelli (17th cent.). On the side walls are two funerary monuments, similar in structure: on the right, the one in memory of Luca Niccolò Recco, Bishop of Ripatransone from 1747 to 1765, with a portrait executed by Ripan Angelo Maccaroni (19th cent.) and an epigraph in Latin; on the left, the one in memory of the parish priest Fr. Vagnozzo Pica, founder in 1615 of the Congregation of the Ripan Oratory, with an epigraph also in Latin. Four small paintings (17th-18th centuries) of devotional character are also visible in the Chapel. Restoration of the architectural structure was done in 1999.

First chapel on the left - Baptistery. It was built in honor of Saints Ignatius and Francis Xavier by Teodoro Condivi, whose coat of arms is in the left wall. In 1938, the year the church became the seat of the pievania of St. Benigno, the chapel was tra- sformed into a baptistery, and the titular canvas was replaced with the sculptural group the Baptism of Jesus in the Jordan River by Uno Gera.

The beautiful chancel (1755) with painted mirrors has a modest liturgical organ, built in 1856 in Notaresco by Vitale de Luca.

The sacristy was completed in 1726; the decoration of the lunette pavilion vault, was executed by Vibi to a design by Bonomi; the fresco painting in tempera grassa, was executed at Tognani's expense by Gian Domenico Monsignori of Sant'Elpidio, who painted in the center the Virgin and Child Appearing to St. Philip (copy of a painting by Reni), and around it in eight mirrors, the three theological virtues, the four cardinal virtues and the virtue of penance; on the walls were painted eight portraits (four remain) of six Philippine cardinals, Fr. Pietro Consolini protector of the congregation, of Bartolomeo Vegezi.
The frescoes and stuccoes were restored in 1997 by Osvaldo Pieramici.
The veneered walnut cabinets were made (1735-1738) by Domenico Pettinelli of Ponzano di Fermo; some shelves hold the lipsanoteca. Above the door to the belfry, placed by parish priest Don Antonio Capriotti in 2001, is displayed the plan (scale 1:20) for the decoration of the church's vault, executed in 1944 by painter and decorator Dante De Carolis (Acquaviva Picena, 1890 - Bologna 1975), brother of Adolfo, commissioned by parish priest Don Guerino Capriotti.

Leaving the Church of St. Philip, down a short but steep descent, one can admire the Monument to St. Philip Neri, inaugurated Dec. 8, 1997, with a bronze sculptural group by Giuliano Pulcini.
