Why the Mountains Mattered
The Serra da Estrela's isolation offered Jewish and later crypto-Jewish communities a degree of distance from royal and ecclesiastical oversight that lowland towns could not. Wool trading, a dominant regional industry, brought Jewish merchants into these highland towns well before the fifteenth century, and their presence outlasted the 1497 conversions in altered form.
Belmonte's synagogue, rebuilt in the twentieth century on the site of long-standing secret worship, is the most visible expression of this continuity, but Covilhã and Guarda retain their own quarters and street patterns.
