Introduction The site of Tróia is located in the southwestern coast of Portugal on a sandy peninsula that separates the estuary of the Sado River from the Atlantic Ocean (fig. 1 and 2). In Roman times this sand spit was probably still a line of islands and the Roman settlement was possibly in the island of Achale referred in this area by Rufus Avienus in Ora Maritima (v. 182-184).
