The Museum of Art Nouveau and Art Déco of Salamaca is a museum of decorative arts from the last decades of the nineteenth century to the Second World War. The museum mainly collects utilitarian objects conceived according to careful aesthetic criteria.

Thanks to the nineteen collections gathered here, the visitor can have an overview of the production of the European decorative arts workshops of the Nouveau and Déco period. Exhibited here: jewels by Masriera or Faberge, iridescent glasses from the Loetz, Kralik, Pallme König workshops or the Nancy school with pieces by Émile Gallé, the Daum brothers or Paul Nicolas. Furniture by Homar, Majorelle, Busquets. Porcelains by Rosenthal, Royal Copenhagen, Mariano Benlliure, Gustave Guetant or Zuloaga. The collections that Casa Lis preserves show the trajectory of important authors such as Émile Gallé with his laminated glass and refined furniture or the evolution of René Lalique who, starting from Art Nouveau jewels, guided his creativity in glass design in the following decades

Also interesting is the collection of French porcelain dolls of the s. XIX, defined by experts as the best collection on display to the world public.
