Discover Mértola: Castle, Archaeology and Crafts

Discover Mértola through several themes: its position above the Guadiana, its castle and archaeological remains from different periods. White houses rise above the river. Historically, Mértola was the northernmost port on the Guadiana; the region’s heavy ores were transported from here to the sea. The riverfront is therefore part of both the townscape and the history of ore transport. The castle complex, religious sites and workshops offer different ways to explore the town.

Castle and Historical Layers

Castelo de Mértola stands on a rocky hilltop. The complex includes an Alcáçova, an enclosure, square towers and a keep. The walled area covers approximately 3,000 m²; the castle is classified as a National Monument. In the 14th century, it was the national headquarters of the Order of Santiago. This was an important historical chapter, but the remains in the castle area reach further back.

Before it was militarised in the 11th century, the fortified area contained an Islamic residential quarter. A Christian religious complex was built in the Alcáçova area between the 5th and 6th centuries. It included a basilica, two baptisteries and a cryptoporticus. A baptistery was used for baptism. The complex’s different construction and use phases provide several historical points of reference, rather than limiting its history to its time as the order’s headquarters.

During excavations in 2022, a mosaic floor was uncovered in the basilica. Its design features rich geometric patterns, and several circular medallions depict different bird motifs. The mosaic floors in the religious complex also have parallels at other sites in the Mediterranean region. Visitors interested in archaeological details will find a concrete example here of how design motifs can be described and placed in a wider regional context.

Archaeological Remains in Mértola

Religious buildings from different periods also stood on the site of the Núcleo Museológico da Igreja Matriz: a Roman temple and a Christian church dating from around the 4th century AD. These are distinct from the preserved architectural remains of the Casa Romana, which show a Roman house dating from the 1st to the 4th century AD. In the impluvium stands a statue of a togatus from the 1st century BC, depicting a man dressed in a toga. These dates place a significantly earlier historical marker alongside the remains of the house.

Crafts and Local Cuisine

At the Oficina de Tecelagem, the entire wool-making cycle is kept alive through traditional production techniques and historic decorative themes. Wool-blanket weaving is one of the oldest traditional crafts in the municipality of Mértola. The subject encompasses both the processing of the material and the techniques and motifs that shape the textile craft. Visitors can meet craftspeople in Mértola’s workshops and discover traditional crafts.

Another workshop story is told by the Forja do Ferreiro, which presents a traditional blacksmith’s workshop preserved as it was left by its last master, “Ti Brito”. It complements the textile tradition with a different kind of workshop. Local cuisine is another way to connect with the area: in Mértola, you can try Alentejo cooking. No particular dish or restaurant is specified.
