The church of San Paolo is located in the old town of Olbia and was built on the ruins of a pagan temple from Roman times, probably dedicated to Hercules.
The church of San Paolo is a tourist destination in Italy that probably dates from the Middle Ages, is mentioned in documents from the fifteenth century but was heavily restored and modified in the mid-eighteenth century, according to the baroque style.
In 1939, the building was expanded. The Baroque interior was decorated with frescoes in the sixties by the painter Alberto Sanna (1929-2010).
