Basilica di San Simplicio

As the oldest church in Olbia, Basilica di San Simplicio dates back to around 1100 AD and was constructed over former Greek and Roman cult grounds. This historic Romanesque-Pisan church once served as the cathedral of Gallura and showcases an austere stone facade alongside a three-nave interior divided by alternating columns and pillars.

Commenters largely bypass discussing the church itself, choosing instead to voice skepticism about Olbia's overall appeal and correct regional beach boundaries. Multiple locals highlight intense parking enforcement and practically nonexistent parking spaces across the broader town.
