Adega Mayor
Adega Mayor opened its doors in 2007 at Herdade das Argamassas, in Campo Maior, and presents itself as the first signature winery in Portugal: the building is by architect Siza Vieira. It was born from a dream of Rui Nabeiro, founder of Delta, and realised with his granddaughter Rita Nabeiro; the property extends over 350 hectares of montado, riverside galleries and farmland.
