The Castle of Alcantarilha is a medieval fortress and its remnant walls in Portugal, in the civil parish of Alcantarilha, municipality of Silves, in the Portuguese Algarve region of southwestern Iberia. It is a little-known monument, now in ruins, used for the protection of the people of the village and surrounding area from attacks by north African pirates.
History
The ancient fortification had its base in a Lusitanian castro settlement, that likely existed between the Neolithic to Chalcolithic transition. It was conquered by the Romans, in 198 AD, and transformed into a military base that was served by the ports of Armação and Pera. During its occupation by north African Arabs in the 12th century, the ancient stone walls were constructed, allowing the protection of the space until the 13th century. It is likely that the civil parish/village first received its name from the Arabic "al-qantarâ", named from a local bridge, on the road between two of the more prestigious provinces of Al-Andalus. The castle was conquered from the Moors by D. Paio Peres Correia, during the reign of Afonso III of Portugal, who sought to command the area by re-building the castle walls. The walls were strengthened and remodeled during the 16th century, under King Sebastian of Portugal, who controversially resulted in the dis-figuration of the Muslim castle. In 1573, when the monarch passed through the locality, he was determined to improve the redoubt, whose strategic importance continued during this epoch: it was seen as a bastion to maritime attacks and guarded areas that could be used as eventual disembarkation points. Although, there were reports that the structure sustained major damages following the 1755 Lisbon earthquake there were no documented resources that confirm the extent of these damages. Yet, it is clear that its decline began after this period. It was similarly restored after the Portuguese Restoration Wars in order to defend the region from Spanish attacks.
Architecture
The original structure of the Castle, its formal layout and extent are still unclear, owing to its destruction and degradation. Many of the typical features of the medieval castle are missing, including towers, doors and complimentary systems of defence. The ovular layout of the streets of Alcantarilha presuppose a Gothic layout to the structure, that may have occurred following the invasions of King Afonso III of Portugal. The castle consists of little more than a limestone wall to a height of. A simple door in the southeast and a rectangular window-like slit in the northwest are the only vestiges of the battlements. Another segment of the wall is addorsed to the northwest corner of a courtyard of a two-story residential building, while to the southeast, in the local market, there are wedges of masonry painted yellow and clinched into the eaves and gabled roof. The castle continues to wait for formal archaeological investigations within the village in order to determine the extent of artefacts and vestiges of this structure.
