Alentejo Region

Alcácer do Sal’s history stretches back over 2,700 years, making it one of Portugal’s oldest continuously inhabited settlements. Founded by the Phoenicians and later occupied by Romans and Moors, the town flourished as a strategic port on the Sado River, facilitating trade between the Atlantic and the interior. The imposing Castle of Alcácer do Sal, perched on a hilltop, dominates the skyline and offers panoramic views over the river, rice fields, and surrounding plains. The castle’s ramparts, towers, and archaeological crypt reveal layers of Roman, Moorish, and medieval occupation, while the adjacent Pousada provides a unique opportunity to stay within the historic walls.

The town’s historic center is a maze of narrow streets, whitewashed houses, and lively squares. The Church of Santa Maria do Castelo, the Chapel of Senhor dos Mártires, and the Igreja da Misericórdia showcase a blend of architectural styles and religious art. The Cripta Arqueológica de Alcácer do Sal is a fascinating underground museum displaying artifacts from the town’s ancient past, including Roman mosaics and Moorish ceramics.

Alcácer do Sal is also known for its connection to the Sado River and the surrounding wetlands, which are part of the Reserva Natural do Estuário do Sado. The area is a haven for birdwatchers, with flamingos, storks, and herons frequenting the marshes and rice paddies. Boat tours on the Sado offer opportunities to spot wildlife and enjoy the tranquil scenery. The nearby Palafita da Carrasqueira, a unique stilted fishing village, is a photographer’s delight and a testament to the region’s maritime traditions.

The town’s culinary scene features Alentejo specialties such as rice dishes, grilled fish, and regional wines, best enjoyed at riverside restaurants and local taverns. Alcácer do Sal hosts regular markets, food festivals, and cultural events celebrating its agricultural and maritime heritage.

Outdoor activities include cycling along the river, hiking in the surrounding countryside, and exploring the nearby beaches of Comporta and the Alentejo coast. The town’s relaxed pace and friendly community make it an inviting base for exploring the wider region.

Getting to Alcácer do Sal is easy, with the town located about 90 kilometers south of Lisbon and accessible by car, bus, or train.
