Alcácer do Sal is a small historic city located near the Sado river delta, just a few kilometres east from the Tróia peninsula and city of Setúbal (40/50 km) and a few more from Lisbon (90 km). It was for many years an obligatory stopping point for those travelling north/south through Portugal (the main national road passes here), especially during the summer season when northerners go south looking for the marvellous Alentejo west coast or the crowded Algarve beaches and nightclubs.
