The building is housed in the former school of the Convent of the Mercedarian Sisters (1893). Its conversion into a museum has resulted in a distinctive aesthetic that combines traditional and contemporary materials.
The Expressionist character of the building, represented by weathered Corten steel with its distinctive rusted appearance and polished concrete, enters into dialogue with the historic brickwork and white walls, evoking the spirituality and serenity of the monastic surroundings.
