Mértola Castle
Beja
Mértola Castle, located in the municipality of Mértola in Beja district, Portugal, is a striking medieval fortress that dominates the historic town center. Its origins trace back to the Phoenician-founded settlement of Myrtilis around 318 B.C., evolving through Roman, Visigothic, and Islamic periods. The castle's current structure largely reflects Muslim military architecture from the 12th century, including the ribat and fortified walls built during the Almohad dynasty. After the Christian reconquest in 1238, it became the seat of the Military Order of Santiago, which commissioned key constructions such as the keep tower in 1292. The castle features a prominent keep tower with an inscription attributing its construction to João Fernandes, the first master of the Order in Portugal. Over the centuries, it underwent multiple enhancements, reflecting its strategic importance on the frontier with Spain. Although its military role diminished by the 18th century, the castle remains a symbol of Mértola's rich cultural heritage and is a central attraction within the town's heritage circuit. Today, it houses exhibitions that detail its evolution and the Order of Santiago’s presence, offering visitors a deep insight into the region's layered past.

Historia
The site of Mértola Castle has been continuously occupied since the Iron Age, with fortifications dating back to between the 6th and 2nd centuries B.C.
The Phoenicians established the settlement of Myrtilis in 318 B.C., which later flourished under Roman rule as Myrtilis Julia.
Following the decline of the Roman Empire, the area was occupied by Suevi and Visigoths before falling to Muslim forces in 713.
The castle was constructed during the Islamic period, incorporating earlier Roman materials and defenses.
It became a key fortified city within the Gharb al-Andalus region, especially during the Almohad dynasty in the 12th century.
The Christian reconquest in 1238 transferred control to Portugal and the Military Order of Santiago, who expanded and reinforced the castle, including the construction of the keep tower in 1292.
The fortress retained military significance until the 18th century, after which it gradually fell into neglect until its 20th-century classification as a national monument.
