The riverside and historic centre of Alcácer do Sal form the gentle heart of the town — a sweep of low, white houses along the bank of the river Sado, beneath the castle hill.
Alcácer is a quiet, white town, and its character is best taken in slowly: a walk along the riverfront, where the river is wide and calm, and through the narrow streets that climb towards the castle. The Sado has shaped the town since antiquity, when it was a busy river port; an emblematic metal bridge crosses the river here.
The identity of Alcácer is bound to its landscape. Its name carries the word 'do Sal' — of salt — and the town's historic wealth came from fishing and salt, and, from the nineteenth century, from rice grown in the fields of the estuary. The riverside, the white houses and the calm of the Sado give Alcácer a distinctive, restful charm, and the historic centre is the natural place to begin a visit.

The town's historic wealth came from fishing and from salt — preserved in the name 'do Sal', of salt — and, from the mid-nineteenth century, from rice cultivation in the fields of the Sado estuary.
