Southern Tuscany is home to a handful of wineries, which are often described as wine cathedrals. The Petra vineyard near Suvereto (by architect Mario Botta) is an interesting example of this new approach in winery architecture. 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. Vittorio and Francesca Moretti (the father and daughter team behind the Petra winery) where largely involved in architect Mario Botta's project. It was clear from the start that the winery was going to be built with the prefab building parts the Moretti family had made their success with. Also an idea of Vittorio Moretti was the long, slightly theatrical tunnel dug into the hill, serving as a natural wine cellar lined up with barriques.
