I was wondering if anyone has seen scholarly work on these 'armários secretos' in Portugal? A number of things seem problematic to me about the claim they are 'hechals' (synagogue cabinets for the Torah scrolls), not least that they are fairly obvious and damning evidence of Judaism. But also that there seems to be no evidence of doors or any fittings and there is no evidence of Hebrew scrolls in Portugal after the Conversão Geral - possession of which would also be pretty damning. There is no evidence given of their physical siting in the building or orientation, nor any evidence that they could be used for other purposes. Are these possibly genuine or yet more Jewish tourist sites?
