Chiesa di Santa Sofia in Benevento

You're standing at the church of Santa Sofia in Benevento, one of the most remarkable early medieval churches in Italy. Start with the façade. It's Baroque, and much younger than the church itself. But set into it is an older Romanesque portal. In the half-moon panel above the door there's a thirteenth-century relief: Christ enthroned between the Virgin, Saint Mercurius and Abbot Gregory.
