A story of fire and passion. The impressive basilica of Sant'Antioco di Bisarcio stands, like a castle, overlooking the plain of Chilivani, in the territory of Ozieri, a few little kilometres from the town. Around it there is a rural village, once a flourishing centre of cultural and civil life,Bisarchium (or Guisarchum), as well as the home of the episcopal diocese. The church, which was built from volcanic rock and is ten metres high, is one of the most impressive examples of the island's Romanesque heritage. It was partly destroyed by a fire around 1090. The fire destroyed the archives: this is why we cannot establish the date on which it was founded with any certainty.
