Basilica di San Simplicio
Olbia’s top sight is this medieval Pisan-Romanesque church, hewn out of Galluran granite. In the apse there are two 13th-century frescos, the left-hand one depicts San Simplicio, the patron saint of Olbia. The Festa di San Simplicio, Olbia’s biggest festival, is celebrated for three days in mid-May.
