Geography as Protection
The Serra da Estrela rises to nearly 2,000 metres and historically isolated its towns behind poor roads and long winters, a condition that worked against commerce but, by most historical accounts, in favour of communities practising Judaism in secret after the forced conversions of 1497. Villages here were smaller and more self-contained than the port cities, with fewer outside eyes and a slower pace of denunciation to Inquisition authorities based in Coimbra.
This is not to suggest the mountains were untouched by persecution — Inquisition records document cases from towns throughout the region — but the pattern of survival into the twentieth century, most famously in Belmonte, is closely associated with this terrain rather than with the coast.
