Ballao
Ballao, (Ballau in the Sardinian language), is a comune (municipality) in the Province of Cagliari in the Italian region Sardinia, located about northeast of Cagliari, in the Gerrei traditional subregion.
It was founded around 1300, when the inhabitants of the ancient hill village of Nuraxi moved in the nearby plain, nearer to the Flumendosa river, to improve their agricultural output. It is home to the Funtana Coberta, a Bronze Age archaeological site.
Ballao borders the following municipalities: Armungia, Escalaplano, Goni, Perdasdefogu, San Nicolò Gerrei, Silius, Villaputzu.
