About this document. This is the source dossier behind the texts and the narration for this site. It was compiled in August 2026 with AI assistance under named editorial responsibility (see About Heritage Navigator), and it replaces an earlier, AI-generated research report from November 2024 that mixed sourced facts with unsourced and invented material. The dossier was written in Danish as the working document and translated into English for this page; Portuguese place names, quotations and source titles are kept in the original.
Every factual statement carries a source number [n], referring to the source list in section 6, and a confidence grade:
Legends and traditions are kept in their own section, with a source for the fact that the story is told, not for its truth. Claims that could not be verified, or that were rejected, are listed separately so that the reader can see what was left out and why. Quotations are reproduced only where the wording was seen in the source. Dead links are recorded as dead, with the date, rather than omitted; where a page exists only in the Internet Archive, the archive URL is given. Section 5 lists what would take an archive, the municipality, the museum or a historian to settle.
Tuna-fishing camp ("arraial") at Quatro Águas, built 1943-45 by the Companhia de Pescarias do Algarve (founded 1835), after the sea had eaten away the company's old camp for the armação do Medo das Cascas on the Ilha de Tavira [1][2][3]. Designed by the engineer José (da) Sena Lino as a walled, self-sufficient "town" with an industrial half (warehouses, workshops) and housing, school, chapel, cooperative, bakery, bathhouse and medical post for c. 150 families/400-500 people in the season [1][2][3]. Inaugurated 15-4-1945 under the Estado Novo with a secretary of state and the parish priest in attendance; named after the company's long-serving head, Comendador Ferreira Neto [3][4]. Catches fell from 1961; last campaign 1971, closure 1972; in 1975-94 the complex housed returnees from the colonies [1][2][4]. Listed IIP by Decreto n.º 5/2002; since 2000 the Hotel Vila Galé Albacora with a free tuna museum in the old bakery [1][2][12][16]. With the Arraial do Barril one of the last two surviving tuna camps in the Algarve [2].
