Museo de Reproducciones Artísticas is an old-school museum built around high-quality casts and reproductions of major works from classical and Renaissance art. In Bilbao, where the Guggenheim dominates the art conversation, it offers a very different teaching-museum experience.
The collection is most interesting if you enjoy sculpture, art history, or the way museums once used replicas for education. It is also a good Casco Viejo-area stop when you want a quieter alternative to the city's headline museums.
