Castle of Arnóia

About

The Castle of Arnóia, also known as the Castle of Arnoia, the Castle of the Moors or the Castle of Moreira, is a castle located in the civil parish of Arnóia, in the municipality of Celorico de Basto, in the Braga District, Portugal. Built on a rocky spur overlooking the former Vila de Basto, it was one of the main defensive and administrative centres of the Terras de Basto. Its construction is generally dated to the late 10th or early 11th century, during the period of the County of Portugal, before the formation of the Kingdom of Portugal, in a context of expanding castle-building in Western Europe. The castle has been classified as a National Monument since 15 March 1946.

The territory of Celorico de Basto preserves traces of ancient occupation, including prehistoric remains, fortified settlements from the Iron Age and elements from the period of Roman Hispania. However, no ancient structure is securely attested on the exact site of the Castle of Arnóia. The location of the medieval fortress is mainly explained by the defensive position of the rocky spur overlooking the former Vila de Basto.

The origin of the Castle of Arnóia is traditionally placed in the second half of the 10th century, while the surviving Romanesque structure is associated with the 12th and 13th centuries. Its construction is generally linked to the defence of the nearby Monastery of São Bento de Arnóia. It belongs to the wider development of castle-building that marked Western Europe between the 10th and 12th centuries.

Múnio Muniz is sometimes presented as the first commander of the castle. The fortress became one of the main defensive and territorial centres of the Terras de Basto.

The castle is mentioned in the Inquirições of 1258, during the reign of Afonso III of Portugal. These royal inquiries show its integration into the military, fiscal and seigneurial organization of the territory.

At the death of Afonso III in 1279, the castle commander, Martim Vasques da Cunha, came into conflict with the new king, Denis of Portugal, in the context of political tensions linked to the royal succession. This episode gave rise to a local legendary tradition concerning his escape from the castle.

In 1282, Denis leased the domains of Celorico de Basto to Martim Joanes for the sum of 210 morabitinos, with the obligation to recruit a knight responsible for commanding the castle. In 1284, the domains and the castle were leased to the inhabitants of Celorico de Basto.

In 1402, after the accession of John I of Portugal, the lordship of the Terras de Basto was granted to Gil Vasques da Cunha.

During the reign of Manuel I of Portugal, a new foral was granted to Celorico de Basto on 29 March 1520. It established the seat of the concelho at Arnóia, in the place known as Castelo.

The first local administrative and judicial centre thus developed around the castle. In the present locality of Castelo, in Arnóia, vestiges of this early organization still survive, including buildings associated with the court sessions and prison, the gallows, the former pharmacy and the pillory of the former Vila de Basto.

The decline of the site began in the early 18th century. In 1717, the local administrative centre was transferred from the former Vila de Basto to the civil parish of Britelo.

This relocation was confirmed by a provision of John V of Portugal dated 1719, which transferred the seat of the concelho and of the local jurisdiction of Celorico to Freixieiro, in the parish of Britelo, under the name Vila Nova de Freixieiro. This transfer contributed to the decline of the former Vila de Basto, while the administrative centre gradually became established around the present town of Celorico de Basto.

Protection and contemporary restorations

The castle was classified as a National Monument by decree published on 15 March 1946.

The monument underwent consolidation and restoration works during the 20th century, especially from the 1960s onwards. In the 1970s, interventions concerned in particular the merlons and the external access to the tower.

The castle reopened to the public in 2004, after restoration and adaptation works. In 2015, a new campaign of works involved the walls, the tower, the accesses, the visitor routes, lighting and technical networks.
