"Il Castagno" residence is placed in Castagno di Piteccio, an ancient village at five hundred metres on a ridge of the high valley of Ombrone, famous for its salubrious climate and calm.

In the village church we can see a well conserved fresco from Giotto's school, discovered during the last restorations.

Along the small narrow streets of the village. some works by modern artists have been placed in a suggestive way. Among them we can find frescos and sculputeres wich form a magnificent museum of figurative art in the open..
