"Tróia is a peninsula located in Grândola Municipality (parish of Carvalhal), Portugal, next to the Sado River estuary. Tourism is the peninsula's main activity due to its long beaches facing the Atlantic. There is a ferry boat connection between the peninsula and the city of Setúbal. Tróia has important archeological sites dating from the time when the peninsula was an island called Acalá, settled by the Romans." In: Wikipedia
