It is the economic centre of this part of the island (commercial centres, food industry) and is very close to the famous Costa Smeralda tourist area. It was one of the administrative capitals of the province of Olbia-Tempio, operative since 2005 and canceled after a referendum seven years later. A dynamic city, which presents itself as a tourist destination, for the beautiful sea and beaches and also for the large number of places of cultural interest to visit.
Olbia (the name is of Greek origin) is very ancient and was possibly founded by the Greeks, although the name is of Greek origin due to the Greek presence during the 7th century bc, the city was first settled by Phoenicians, according to the archaeological findings. It contains ruins from nuragic to the Roman Era, when it was an important port, and the Middle Ages, when it was the capital of the Giudicato of Gallura, one of the four independent states of Sardinia.
From 1113 it was the episcopal see of the Diocese of Cività (succeeding to the Diocese of Gallura, the 1070 restoration of the Diocese of Fausania, c. 500–750), which was renamed in 1839 as Diocese of Civita–Tempio until its formal suppression in favor of (in fact merger into) the Diocese of Tempio–Ampurias (also integrating the Diocese of Ampurias, which was in personal union with the see of Civita from 1506)
Olbia is the main connection between Sardinia and the Italian peninsula, with an airport (Olbia – Costa Smeralda), a passenger port (Olbia-Isola Bianca), and a railway from Olbia railway station to Porto Torres, Golfo Aranci and Cagliari. There is an expressway to Nuoro and Cagliari (SS131) and national roads to Sassari (SS199-E840), Tempio Pausania (SS127) and Palau (SS125).
Olbia has a Mediterranean climate, with very mild winters, warm springs and autumns and hot summers.
Meridiana Fly has its head office on the grounds of Olbia - Costa Smeralda Airport.
