The Sequerciani Winery, located in Gavorrano (GR), in the hills of the Tuscan Maremma, is primarily underground to preserve the gentle curves of the land. It is the result of a geological architecture that integrates with the landscape without spoiling it. PONZI windows and doors, in terms of type and finish, are perfectly integrated into the structure and have been installed along the entire perimeter of the winery. Inside, paneled Ponzi doors also separate the various spaces and tasting rooms.
