Built in the eighteenth century by Arechi II, the Church of Santa Sofia is one of the most significant monuments of the Lombard period. It preserves fragments of a cycle of frescos depicting stories of Christ, considered one of the most quintessential representations of high-medieval painting. The church, one of the contributing factors that led to Benevento being listed as a UNESCO World Heritage Site in 2011, was linked to a Benedictine abbey which is now home to the Museo del Sannio (The Samnite Museum).
