Olbia, called by the Greeks the "happy city", overlooks the gulf that encloses the beautiful islands of Tavolara and Molara. Known all over the world for the airport that allows access to Costa Smeralda, the city represents a strong industrial and commercial reality, with very important poles for Sardinia, such as Porto Rotondo and Portisco.
Numerous and interesting are the archaeological sites in the area: the nuraghe Riu Mulinu, at the hill Su Casteddu overlooking the Gulf of Olbia, the tomb of the giants of Su Monte de S'Aba and the sac de Sa Tesa. Conquered by the Romans, the city conserves its thermal baths and aqueduct, the only one untouched in Sardinia, and a typical Roman farm in S'Imbalconadu.
