Mario Botta Petra chose to create a powerful symbol within the landscape rather than build a more conventional industrial complex. At Petra the world-class architect went beyond designing an impressive wine cellar, but also included the outlay of the vineyards in his aim to form a contemporary agricultural landscape. The winery sits against rolling hills of vines and it presents itself as a a dramatic cylinder of brick and local Prun stone. Cropped to reveal its sloped elliptical face, the circular crown is bisected by a dramatic staircase and studded with a ring of olive trees and grasses.
