The literal meaning of “Crete Senesi” is Sienese clays. They are, in fact, very distinctive of this area and resemble a lunar landscape. The Crete Senesi are mainly made by “mattaione”, a sediment of marine origin with a high mineral content. All around, human presence is limited: the sound of nature prevails over the handful of buildings, such as old brick farmhouses. You won't find any squares, castles or cathedrals here. During the summer, a gentle wind shakes the golden wheat, giving the sensation of Heaven on Earth!
Nearby there is another peculiar landscape known as the Accona Desert (deserto di Accona in Italian). It is a semi-arid area located in the west and south part of the Asciano municipality. The semi aridity is due to the low rainfall, which is less than 600mm yearly and, as a consequence, the vegetation is scarce. The area is characterized by calanques and dome-shaped formations known locally as “biancane”, where the name derives from the Italian “bianco” (white) due to their light hue. The area has been known since the Middle Ages, as testified by the frescoes of Buon Governo di Siena depicting the Accona Desert.
