Jar of Gesturi
The jar of Gesturi, also known in the Sardinian language Sa jara manna, is the largest of jars. It covers 45 km² divided into the common Gesturi Tuili, Setzu and Genoni. It consists of an immense basaltic lava flow erupted about 2.7 million years ago.
The territory is characterized by the very stony soil, full of small ponds that fill in winter and spring water are covered by a very colorful flora. They are used to drink the last wild horses of Europe: Giara ponies.
Very special are the cork oaks that the strong mistral undertakes to growth skewed (to the east).
