The territory of Olbia has been inhabited since the 8th century B.C. However, the city itself was founded by the Carthaginians no earlier than the 6th century B.C. Right from the beginning, the harbour was of crucial importance to the city’s economy, as its corn export industry constituted its main source of revenue.

The word «Olbia» means «a happy town». Among its significant monuments is the city’s ex Cathedral, situated in the old town and dedicated to St. Simplicio.

Olbia has also become famous thanks to the recent archaeological discovery of 24 shipwrecks – 2 of them dating from the age of Nero and 16 from the 5thcentury A.D. The remaining 6 date back tothe judicial period.
