The building is set on an embankment reinforced by a stone wall. The road alongside it was, for centuries, the main road connecting the Cornappo valley to the ford of the Torre river: built by the Romans, it crossed the Centa, where the family heads would meet to make decisions regarding the community. Archaeological explorations carried out in 1993 revealed a cult building here dating back to the early Christian period (4th-5th century), on the remains of an even older prehistoric construction. In the pre-Romanesque period (10th-12th century), the small church assumed its current size, and in the 14th century, it was adorned with fine frescoes, of which few traces remain. The earliest documents date back to 1281, when Enrico di Qualso, a canon of Cividale, made a testamentary donation to Saint Maurus. In 1336, it is mentioned in the will of Nato quondam Benetto of Nimis, who left "two pounds of oil annually" to the church. The dedication to Saint Maurus can be attributed to the devotion spread by the Benedictines following the Cluniac reform in the 12th-13th centuries. Little remains of the 14th-century church, with a round apse and bell tower: the current building dates back to the 15th-century and has been modified. The building has a single nave with a semicircular apse in squared stone. On the simple gabled facade, there is an architraved door, two lateral rectangular windows, and a central lunette window. The stone bell tower was built in the late 19th century.
