It is the economic centre of this part of the island (commercial centres, food industry) and is very close to the 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. Olbia is a tourist destination thanks to its sea and beaches and also for the large number of places of cultural interest to visit.

Although the name is of Greek origin, due to the Greek presence during the seventh century B.C., the city of Olbia was first settled either by the Nuragics^[7] or by Phoenicians, according to the archaeological findings. It contains ruins from the Nuragic era 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. During the First Punic War, the Romans fought against the Carthaginians and the Sardinians near Olbia, where the general Hanno died in battle.^{[citation needed]}

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).^{[citation needed]}
