With the intention of bringing together under one same roof the entire collection of the extinct Museum of Artistic Reproductions, the National Sculpture Museum made a call for competition that would result in a project to fit out the Renaissance palace of the Count of Gondomar in Valladolid, commonly known as the Casa del Sol. The winner, Juan Carlos Arnuncio, thus makes a new addition to his already long list of interventions on heritage architectures in the region of his birth.
