Diocesan Museum of Sacred Art

The Holy Trinity Church, built in the 16th century, has housed the Diocesan Museum of Sacred Art of Trivento, a town in the province of Campobasso, since 2001. It houses the most significant examples of sacred art from the ancient Diocese of Trivento, mostly from the Church of Saints Nazario, Celso and Vittore. Among the exhibits are three wooden statues dating back to the 14th century, as well as a rich collection of sacred vestments, with a focus on brocades and silk garments adorned with gold and silver, dating from the 16th to the 19th century. In addition, the Museum contains a 16th-century silver reliquary, inside which is the relic that constitutes the Mausoleum's greatest treasure: the Holy Thorn, consisting of a thorn from the crown that Jesus wore during the Passion. The latter was transported to Trivento in the 16th century, after having been kept at Rosello since medieval times.
