Meilogu

The territory of Meilogu is predominantly volcanic and the conical hills give it a unique appearance in the context of a geologically ancient land, so much so that it is given the nickname of Sardinian Auvergne. Its soils are also among the most fertile on the island. The main peaks are mount Santu, mount Pelau and mount Traessu, all extinct volcanoes standing just over 700 metres high (source: Wikipedia).
The municipalities forming part of this territory are: Ardara, Banari, Bessude, Bonnanaro, Bonorva, Borutta, Cheremule, Cossoine, Giave, Ittireddu, Mara, Mores, Padria, Pozzomaggiore, Romana, Semestene, Siligo, Thiesi, Torralba.
Volcanic craters of Meilogu are natural monuments:  the area of Mount Annaru (Giave) falls within the region of Meilogu-Logudoro, of particular interest for its morphology and geological sequences: it is characterized by a cover of oligo-miocene volcanites  overlying the Paleozoic crystalline base. Above sediment, lava and deposits. Mount Annaru, located just north of Giave, at 491 m a.s.l., is a splendid example of a volcanic cone, which can be attributed to post-Miocene eruptive activity. Its isolated position makes it easily recognisable. It still has well-preserved internal and external slopes and a large eruptive mouth in the shape of a caldera which spewed out the lava that gave rise to the basaltic plateau situated N-NE of the hill of Giave. Inside the crater, during winter, a small lake forms.
