The church of San Rocco in Montereale Valcellina is located just before the Ravedis narrows, in a decentralized position compared to the current town. Its antiquity is confirmed by the presence of the cemetery, as was customary in the old parish churches, one of the oldest and most important in the diocese of Concordia. Near the area, homes and necropolises from the Bronze Age to the Roman Age, ritualistic objects and a small altar to the God Timavo have been brought to light.
Initially dedicated to Santa Maria Assunta, it was then dedicated to San Rocco. Named in a papal bull of Urban III in 1186, it was central to the evangelization of the surrounding area as early as the 5th century. Archaeological investigations have identified three phases in its construction: the first, early Christian, dating back to the 5th century, when it was dedicated to the Assumption of the Virgin; the second, medieval, from the 12th century, of which the walls of the nave remain; the third, the Renaissance one from the beginning of the 1500s, which determined the current configuration of the building and the change of name, to San Rocco. The building was enlarged in the 18th century and restored in 1969. The smooth façade is characterized by a simple portal with stone pillars and architrave. A second entrance and three windows open on the right side, a window also opens in the presbytery. There was also a bell tower, probably from the late medieval period, which was demolished in 1983.
The internal environment has a rectangular hall with a wooden truss roof and two side chapels along the left side. The rectangular presbytery has a sail roof and is higher than the hall. The two rooms are separated by a pointed arch. The sacristy body (16th century) is attached laterally.
Despite the simplicity of the external appearance, the church houses a pictorial jewel inside: it is the decoration of the choir created by Giovanni Maria Zaffoni known as Calderari (Pordenone, circa 1500 - after 1570), between 1559 and 1563, recognized as one of his most important works.
