Caorle is a very ancient town, whose documented origins date back to the Roman times.
However, the most ancient findings in the territory date back to a period between the XIV and the XII century bC, called the Bronze Age; they have been brought to light by recent excavations in San Gaetano, a rural hamlet 5 Km from Caorle centre: ceramic artefacts, as well a bronze axe and a deer corn comb of great value have been found. Another remarkable discovery is the shipwreck that has been recently found 13 miles off the coast of Caorle, dating back to the I century bC, witnessing the presence of sea trade in Roman times.
In fact the area appertained to the colony of Julia Concordia (now Concordia Sagittaria), about 25 km from Caorle, which was the crossroads of two important Roman consular thoroughfares: via Annia and via Postumia. A port probably linked Concordia to the sea across the river Reatinum, whose mouth was probably near Caorle.
However, a considerable amount of time before the Romans, important settlements existed in this area. The discovery of a proto-historic village dating back to the Bronze Age (at least 1500 years before Christ) in the countryside surrounding San Gaetano, bears witness to this.
After the fall of the Roman Empire, Caorle became a place of refuge for the inland population that escaped the barbaric invasions. It transformed into one of the most important cities on the coastline, contributing to the foundation of Venice, to which its history had been connected for a millennium.
After the Hapsburg dominion in 1800, the two world wars, and by the years approaching 1950, its modern history has been linked to the tourism economy that over a few decades has strongly increased its social development.
