A plain building that was once the Royal Silk and Textile Workshop now houses this foundation, dedicated to exhibiting and promoting research into the work of Portuguese modernist Maria Helena Vieira da Silva and her Hungarian husband and fellow painter Arpad Szenes. Although the couple lived in France for many years and played a central role in the School of Paris, they're also iconic figures in Portugal. As well as housing and displaying its large permanent collection of their works, the foundation puts on regular exhibitions of artists with links to the couple, such as Fernand Léger and Marc Chagall.
