Olbia was possibly founded by the Greeks and was an important port. During the Roman Era it was settled by Phoenicians and Carthaginians. The main sight of Olbia is the Romanesque former cathedral of San Simplicio from the 11th – 12th century.
Some sites of archaeological importance from the legendary Nuraghic civilization are the Riu Mulinu nuraghe (Cabu Abbas), the Tomb of the Giants of Su Monte de S'Abe and the sacred nuraghic well of Sa Testa, and from the Roman Era the Roman Aquaduct and the Roman farm at S'Imbalconadu . Recently opened and surely worth a visit is the archaeological museum, situated on the little Island of Peddone.
The coastal territory of Olbia is one of the most beautiful in Sardinia and shows up sandy beaches and coves, separated by particulary fromes cliffs and Granite rock formations. To enjoy the beautiful sea we recommend beaches like the ones of Pittulongu, Bados, Marinella, Saline and Porto Istana.
Natural lovers shall visit the Tavolara island, a limestone massif 5 kilometres long and 1 kilometre wide. The island and the surrounding waters are part of the Tavolara and Punta Coda Cavallo Marine Preserve created in 1997.
