Under the waters of El Port de la Selva bay, resting for more than 2,000 years, the Cap del Vol, a Roman vessel that sank with its cargo of wine and which has been baptised with the name of the beach where the wreck remains. From the outset, the researchers realised that the Cap del Vol was not a conventional Roman ship: the characteristics of its naval architecture were quite different from other wrecks (sunken ships) from the same period.

In particular, the draught of the vessel (the distance between the waterline and the keel) is lower than that of other ships and its keel is not pronounced. Features that made it ideal for sailing in shallow waters or in wetland areas and the scholars believe that in reality it was a ship built by the indigenous population of the area.

El Cap del Vol was carrying a load of wine stored in amphora and it is believed that it made the trip between the Catalan coast and that of Narbonne. Among the most remarkable finds there is a coin from Arse (Sagunt) and the cork in one of the amphora.
