The Alliance Underground Museum is an exhibition space, developed along the traditional cellars of the Alliance Wine of Portugal. Contemplating eight different collections, this museum equipment covers areas such as archeology, ethnography, mineralogy, paleontology, tiles, ceramics and tin covering an impressive time span over millions of years. Inserted in the great universe of the Berardo Collection, these collections result from the constant care of the collectorJosé Berardo, in immunizing pieces and works of art, from multiple origins and species, with sometimes historical, sometimes sentimental meaning.
