Castelo de Arraiolos

High on Monte de São Pedro, north of the town, Arraiolos Castle preserves the memory of the old walled settlement. Commissioned by King Dinis in the early 14th century, it was based on a contract signed in 1305 between the king, the mayor, the judges and the municipal council, to build the defensive enclosure. Construction began in 1306, and the complex includes the wall of the former settlement and the Paços dos Alcaides. Its elliptical form follows the gentle relief of the hill, creating a rare silhouette in the Alentejo landscape. Among the elements still recognisable are the Keep, the Gate of Santarém and, inside, the former Church of Salvador, from the 16th century. Classified as a National Monument since 1910, the castle also recalls Nuno Álvares Pereira, to whom King João I donated it in 1387.

Why it matters

The Arraiolos Castle is one of the most unique castles in Portugal, not only because of its picturesque location in the Alentejo region but also due to its rare circular shape, uncommon among Portuguese medieval fortifications. Its construction dates back to the 14th century, ordered by King Dinis, who had it built on a hill overlooking the town of Arraiolos and the vast Alentejo plains. Its primary purpose was to protect the inhabitants and control the surrounding area, as Arraiolos was strategically positioned. However, human occupation of the area dates back to the Bronze Age, with ancient civilisations leaving traces nearby. During the Reconquista, the town and castle became an important part of Christian defences, especially after the final reconquest of the region in the mid-13th century. After centuries of strategic importance, the castle was gradually abandoned in the 17th century, losing its military function.

Architecture and history

The Arraiolos Castle stands out for its circular design, one of the rare examples of this type of architecture in Portugal. The well-preserved walls encompass a large area and are made from local limestone, combined with "taipa", a common technique in the Alentejo region due to the availability of materials. The perimeter features defensive towers and battlements, offering impressive views over the surrounding landscape. In the centre of the castle are the ruins of the old Church of Salvador, built in the Gothic style. Although in ruins, interesting architectural details can still be seen, such as pointed arches and decorative elements that reveal the site's religious importance during medieval times. Another architectural highlight is the Porta da Vila, the gate that provides access to the castle’s interior. The robustness of the walls and their circular configuration give it a unique presence, and walking along the walls is a fascinating experience for visitors.

For visitors, the Arraiolos Castle offers a panoramic 360-degree view over the vast Alentejo plains and the charming town of Arraiolos.

Close to the castle, visitors can explore the historical centre, with its whitewashed houses and winding streets that preserve the Alentejo's charm.
