Originally dedicated to the Spoletan martyrs Concordio and Senzia, the church is one of a series of palaeochristian basilicas that were built around Spoleto in the first centuries of the Christian period. The present title testifies to the importance that the church used to have among the Longobards, in consideration of the particular cult that this people used to have for the Saviour.
The duchy’s upper echelons were probably responsible for the 7th/8th-century renewal that gave the building its uncommon beauty. The façade features plant-like volutes carved on the three portals’ architraves, whose beauty would inspire generations of masons, who would later reproduce those patterns in many Romanesque churches in the area.
The inside features a nave and two side-aisles, with a presbytery set on columns that support an architrave, a remarkable sample of the skills of local workers in using spolia elements, harmoniously reassembling them in a new whole.
Along with the Clitunno Temple, the church represents one of the main Longobard architectural evidences in the Langobardia Minor, hence their insertion into the UNESCO WHL in June 2011, under the name of “The Longobards in Italy: Places of Power”.
