Historical Background
Medieval Lisbon supported multiple Jewish quarters at different periods, the result of the city's growth and successive royal decisions to relocate or expand the community's designated districts; sources place an early Judiaria in the area associated with Alfama and the lower city near the Sé cathedral, predating the larger fifteenth-century Judiaria Grande established near the Rossio under King Fernando I in the fourteenth century. Lisbon's Jewish population, one of the largest in the kingdom, included prominent physicians, financiers and royal advisors who served the Avis dynasty directly.
The catastrophic Lisbon massacre of April 1506, in which a mob killed a large number of New Christians accused of secretly practising Judaism, took place chiefly in the lower city and remains one of the darkest events in this history; it is treated as a distinct site of memory elsewhere in this atlas rather than folded into the general Judiaria narrative.
