Visit to the Roman Ruins

The Roman Ruins of Tróia are a unique heritage, included in the Indicative List of Portuguese World Heritage and National Monument since 1910. During the period of Roman occupation, dated back from the first century to the sixth century A.D., Tróia was an island in the Sado delta, named Acála Island. Its uniqueness is due to the high concentration of salting factories, where sauces were made and salted with fish, which were then exported in great quantities throughout the Empire. An unequaled production capacity, which corresponds to the largest production center of salting fish from the Roman world.
