Its intricate and steep paved roads are arranged in amphitheatre style over a very sloping territory: you will enjoy splendid views of the valley below, which is covered in woods. Ozieri is a little town with over ten thousand inhabitants. It is the most highly-populated in the Logudoro area and is located approximately 50 kilometres from Sassari. It was already the administrative centre of Mount Acuto in the 14th century and in the 18th century it became the second most important town in the northwestern area. Its urban fabric is enriched by pavements that open up into clearings, little terraced squares and gardens and it features roof-terraces and nineteenth century loggias. In the old town centre, one of the most prestigious civil buildings is Palazzo Costi, while among the town's historical locations not to be missed are the Borgia prisons. The main place of worship is the cathedral of the Immacolata, built in the 15th century and transformed in the 19th century. The town is dotted with churches, starting with that of Santi Cosma e Damiano (16th century) and that of the Rosario (17th century), but the most important ones are outside of Ozieri. The most famous one, which is one of the maximum expressions of Romanesque style in Sardinia, is the majestic basilica of Sant'Antioco di Bisarcio, overlooking the plain of Chilivani.
