Crete Senesi translates to "Siennese clays". The appearance of the landscape is often described as lunar due to the distinctive gray coloration of the soil. Depending on the time of day, the soil can also have a beautiful ochre cast that is a sight to behold. The clay is formed from the sediment of the Pliocene sea which existed in the area approximately 3 million years ago. The world's most prized landscape photos often are taken in Crete Senesi. It is also a favorite area for painters to set up their easels. The soil from this area was used to create the famous "Sienna yellow" by Renaissance artists.
Crete Senesi is one of the most magical landscapes in all of Tuscany. The spirit of the Renaissance is preserved here and it is not to be missed.
