The Roman Bridgeknown as "Su Ponti Mannu"(the Great Bridge), is one of the oldest and most significant testimonies to the island's history. Built in 1st century A.D.when the island was called Sulky and was one of the most important centres of the western Mediterranean, the bridge was the fundamental link between the island of Sant'Antioco and the mainland of Sardinia. It was part of the Roman road that connected Karalis, ancient Cagliari, to Sulci.
Today, a short section of the original Roman roadpartially submerged but clearly recognisable on days when the tide is low. Unlike other Roman bridges built to cross rivers or differences in level, this bridge actually connected an island to the mainland by crossing a series of islets forming an isthmus. Over the centuries, the bridge underwent damage and restoration, with work documented from at least 1774 and further work in the 19th century.
The site is set in a lagoon landscape and the original arches are still visible next to the modern bridge, offering visitors a tangible glimpse of Sant'Antioco's Roman history.
The Roman Bridge is a must to immerse oneself in the island's most ancient history and admire a unique masterpiece of Roman engineering in the Mediterranean.
