Castle of Amieira do Tejo
building in Nisa, Portalegre District, Portugal
The Amieira do Tejo Castle is a Portuguese castle in the civil parish of Amieira do Tejo, municipality of Nisa, in the antique district of Portalegre, approximately 200 kilometres from the city of Lisbon.
History
In 1232, owing to a regal charter issued by King Sancho II, the dominion of the Knights Hospitaler expanded their influence into the south; the religious order expanded into the villas of Amieira, Gavião and Crato. In Crato, they carried out construction projects, to establish their institutional seat, just after the donation.
The construction of the castle in Amieira only developed a century after the Hospitalers had taken possession of the territory. Its construction was the responsibility of Álvaro Gonçalves Pereira, son of the Archbishop of Braga Gonçalo Pereira, prior of the Order of the Hospital and father of the future-constable of the kingdom, Nuno Álvares Pereira. It was Gonçalo Pereira who had originally been responsible for transferring the Order from Leça do Bailio to Crato e Mártires (in 1356). The castle of Amieira was constructed as part of the settlement's place in the new function of the Order: to assist the travelling pilgrims. Three years following this change in roles, King Peter I visited the fortress, whose construction was already quite advanced. But, by 1362, the project had not been concluded: Álvaro Gonçalves Pereira had taken a lot of pacience in the construction and evolution of the castle, until his death in 1375.
The fortress suffered various modifications over the centuries.
This brief starts where responsible research should: with the source description of “Castle of Amieira do Tejo” as building in Nisa, Portalegre District, Portugal. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as building in Nisa, Portalegre District, Portugal. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q5050365. Authority coordinates are 39.508, -7.816. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1232, 1356, 1362 and 1375.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
