The white houses of Mértola sit above the Guadiana. The river is also part of the town’s economic history: Mértola was the northernmost port on the Guadiana and served as a route for transporting the region’s heavy ores to the sea. The riverside location and its former role in ore transport are therefore two distinct aspects of the town’s history. The castle, religious architectural remains, Roman structures and workshop traditions tell further chapters.
The Castle and Its Older Layers
Mértola Castle stands on a rocky hill. Its complex includes an alcáçova, an enclosure, square towers and a keep; it is classified as a National Monument. The walled area covers around 3,000 square metres. The description of the castle thus ranges from its specific architectural features to the size of its fortified area.
In the 14th century, the castle was the national seat of the Order of Santiago. Before it was militarised in the 11th century, an Islamic residential quarter stood within the fortified area. These historical uses illustrate different chapters in the history of the castle complex, rather than limiting it to its defensive architecture.
Religious History and Mosaics
A Christian religious complex with a basilica, two baptisteries and a cryptoporticus was established in the area of the castle’s alcáçova between the 5th and 6th centuries; the basilica is believed to have been built during this period. Excavations in 2022 uncovered a richly patterned geometric mosaic floor in the basilica. Several circular medallions depict different bird motifs. The mosaic floors of the religious complex also have parallels at other sites around the Mediterranean.
The site of the Núcleo Museológico da Igreja Matriz was occupied by a Roman temple and, from around the 4th century AD, a Christian church. The basilica in the religious complex is reached via the path to the Old Cemetery; check before your visit whether access is currently possible.
Roman Structures and Crafts
The Casa Romana displays the preserved architectural remains of a Roman house dating from the 1st to the 4th century AD. In the impluvium is a statue of a togatus—a figure depicted wearing a toga—dating from the 1st century BC. The statue is therefore dated earlier than the architectural remains of the house.
The Forja do Ferreiro presents a traditional workshop in the condition in which its last master, “Ti Brito,” left it. Another craft tradition is wool blanket weaving, one of the oldest traditional crafts in the municipality of Mértola. The Oficina de Tecelagem keeps the complete wool-making cycle alive using traditional production techniques and old decorative motifs.
