Castle of Aljustrel

The Castle of Aljustrel is a medieval ruin on a hilltop in the Baixo Alentejo region, rising about 247 meters above sea level. Its walls display different construction phases, with later structures visibly integrated into older foundations that reflect various building periods.

The fortification arose during a time when Arab settlers shaped southwestern Portugal, with archaeological evidence dating to the 9th century. Portuguese forces captured it in 1234, and shortly after the king granted it to the Order of Santiago.

The fortification shows traces of Muslim settlement that visitors can observe in its remaining walls. These layers reveal a time when Arab settlers shaped the region and left their mark on local construction methods.

The ruin sits on elevated ground offering views across the surrounding landscape. Visitors should expect uneven terrain and wear sturdy footwear to safely explore the different areas of the remains.

The foundations contain visible sections of taipa construction from Arab settlers, especially in the northwestern, southeastern, and northeastern areas. This earthen brick technique differs markedly from later European building methods and shows the Arab craftsmanship of that time.
