The town lies nestled in a valley at the feet of the Monte Arci Park, under the small Tanca Manna giara on which a fascinating nuraghe was built, and surrounded by woods of holm oak, durmast, cork and Mediterranean shrubs. Siris is a town of some 220 inhabitants 25 kilometres from Oristano. It has been an independent comune since 1961, after having been incorporated into Masullas and Pompu in 1927. Its name comes from the Greek xiris, iris, a flower that flourishes in the area. The local economy is based on livestock farming. The fine pastureland makes for delicious cheeses you can taste in Spring during the Cheese festival. The flavours of Autumn are celebrated during the Quince festival in November, when they are used to prepare a variety of delicacies.
