Museo Diocesano

The Diocesan Museum (D'Museoa) is San Sebastián's specialist repository for religious and liturgical art, growing out of a landmark Eucharistic art exhibition that put the collection on the map. Tucked into the city, it gives you an unusually focused look at sacred objects, vestments, and artworks tied directly to the Basque diocese's history. Quietly absorbing if you're into art history or just curious about the region's deep Catholic heritage.
