Created out of the progressive joining together of several settlements, it is located on the Sulcis plain, near the lagoons of Porto Botte and Sant'Antioco, where you will observe herons and flamingos. San Giovanni Suergiu is a village with six thousand inhabitants and made up of four main districts (San Giovanni, Palmas, Is Urigus and Matzaccara), as well as a myriad of smaller urban concentrations. Its urban history began in the Byzantine age, in the 9th century, with Villa di Palmas di Sols, a village that developed thanks to the abandonment of the ancient towns of Bithia and Sulci. Still remaining from that flourishing period, you can see the ruins of the Palmas Castle (11th century) and the little church of Santa Maria (12th century), the main place of worship of that period.
