The Etruscans lived on the island for many centuries from the 7th
century b.C., onwards, but, due to their custom of building cities out
of clay, which "dissolved" over the years, little trace remains of them
today. However, the necropolies which can still be found testify to the
existence of their lost villages: settlements in Portofferaio, Monte
Castello near Procchio, Volterraio and Castiglione di San Martino. There
was a fortress on Monte di Santa Lucia, rebuilt by the Pisans, and a
temple, possibly dedicated to Tinia, on Monte Serra, near Rio.
