Tróia

Troia was a Lusitanian-Roman station located in the peninsula of the same name, at the edge of the parish of the Carvalhal, in Grândola, in front of the city of Setúbal.

The history of this place dates back to the second century AD, when this settlement already existed, and which would show signs of progress and development in the following centuries. It shows the season signs of decay in the last years of its occupation. Living out of an industrial activity that had its markets outside the peninsula, the decay of the empire and the fall of its western part implied and explain the decadence of the town.

The cetarias, or salting tanks of the fish, still extended in 1858 in an extension of 4 km, according to Carlos Ribeiro. Thus it is concluded that an industrial village was once established there, with a large garum industry and fish preserves, whose production would be exported off the peninsula and therefore also an important fishing center. This Roman center occupied the best area of the peninsula and as the land was not unhealthy, in contrast to Setúbal, the workers would have been recruited among the bordering indigenous settlements, which led to the depopulation of the area according to Roman strategy, referred to by Strabo.

The Lusitano-Roman station of Troia is important in the religious point of view, since besides presenting vestiges of pagan cult and of the Christian, is one of the rare places in Portugal where it is known that there was cult to Mitra, revealed in bas-relief.
