A sprawling 1,555-square-meter (about 16,700 square feet) warehouse space offers an ideal spot for an pop-up art show. Earlier this year, before starting up his car components manufacturing business, owner António Albertino decided to display his art collection inside his newly built warehouse and office, the Adémia, in the medieval city of Coimbra, Portugal. Works by Andy Warhol and John Baldessari and sculpture by Miroslaw Balka, Antony Gormley and Ângelo de Sousa were curated by Delfim Sardo. Designed by Portuguese architect João Mendes Ribeiro, the Adémia's silhouette is the quintessential factory, with pitched roofs resting on top of concrete walls. An aerial bridge across the courtyard connects the office to the warehouse. White walls, pale timber window frames and exposed metal details; it all comes together to make for quite a magnificent backdrop to the artworks.
