The Diocesan Museum of Alba has as its purpose the conservation, study, research and dissemination of the historical, artistic, archival and bibliographic heritage of the Diocese. The Diocesan Museum is structured on seven locations in the area. The headquarters, founded in 2008 in the underground rooms of the cathedral of Alba, consists of an archaeological excavation that allows you to discover a fragment of the history of the city, starting from the Roman age (I-II century AD) up to the foundation of the first episcopal church (6th century). In the exhibition rooms, the Crypt of San Pietro and the Sala dello Stemma, remains of the early medieval liturgical furnishings and the lapidary with Romanesque, Gothic and Renaissance finds are exhibited. Some showcases preserve ceramic materials, textile and glass fragments, painted plasters and coins. With the help of new technologies, such as multimedia stations and an immersive room, the Alba museum also acts as a documentation center and gateway to experience the diocesan territory articulated between Langa and Roero.
