Guests arrive in Piazza San Giovanni, the magnificent Piazza del Battistero, where historic buildings (such as the Palazzo del Magnifico and the Archiepiscopal Curia) are erected and the back of the Cathedral, sparkling with white and black marble and the majestic staircase. At the entrance, the guests can admire the original drawing of the Baptistery of Siena, unfinished due to the plague and two drawings made by famous architects, Louis Khan and Le Corbusier whose originals are no longer in Italy. Once here, guests have to go down, reaching an unique and inaccessible place, where the water once flowed. The "bottini" are buildings of medieval origin that brought water to the city of Siena. You will see a medieval well, an Etruscan hut dating back over 2500 years and a sandstone sediment dating back over 1 million years ago when Siena was below sea level. There you can see historical fossils. After you can enjoy the real and unique experience of the wine tasting in an unique atmosphere combined with our organic olive oil tasting. Once the experience is over, guests can end with a bang.
