The current parish church, the “plebale” church in XIV century with baptismal font and canons, stands, just before the village of Villa San Silvestro, on the ruins of a roman temple, occupying the whole space of the central cell of it (the temple, erected in the melting point between the plain open toward the distant area of Rieti and the mountainous hinterland, was an important economic, cultural and religious center of attraction for local people).

The church of St. Silvestro de Ocrile was already known in 1253 amongst the churches donated by the bishop Accoramboni to Teodino, the Abbot of Saint Eutizio. The Church was rebuilt by Silvestrini in XVI century, but was damaged by the earthquake in 1703.

Today the church has an intact and functioning structure (it was restored in the eighties of the XX century). The plan is quite simple. The floor was made of slabs with 10 master burials. Inside are remains of frescoes from the XVI to the XVIII century. The stoup is from 1577 and the wooden tabernacle, in the shape of a small temple in the manner of the Italian Renaissance architect Bramante, dates back to the end of the same century. It is an octagonal polyhedron. The smallest sides are hollowed by niches and plates, while the biggest ones are hollowed by doors shaped by arches of lunettes. At the corners little columns with composite capitals support the triangular tympanum. The central small door is raised on three steps. The cube is surmounted by a lantern adorned with figures in gold, which overlooks the octagonal dome decorated with fish scales. The lantern is supported by cylindrical ribs at the corners. On the small doors are painted the images of Saint Anthony, Saint Sylvester and Saint Francis. A wooden statue from the XVII century represents the Holder Saint Sylvester, the Pope. The small processional cross is made of brass pod, its sides are decorated with dolphins spirals, dealt with palms; there are also a small shrine in Gothic shape on a seventeenth century brass foot, a monstrance and two chalices of the same century.

Apostolic messengers, visiting the church in 1611, noticed 6 altars; the main one and others dedicated to: Saint Anne, Our Lady of Angels at the left, Saint Nicholas at the right, Saint Salvatore and Our Lady of the Aid near the door with images painted on the wall. They mentioned also the  “old fashioned” baptistery, which someone ordered to replace with a round baptismal font, but the order was never executed. Here had their seat also the Confraternities of the Sacrament and of the Rosary.
