Marrano Museum of Carção, northern Portugal 
(first such museum in the world!)

".....it is thus that Barros Basto, the Apostle of the Marranos, seems alive, contradictory, honest, a hero that struggled to rescue the Marranos, that is, those Jews who during four centuries concealed themselves, passing and re-creating, from generation to generation, a tradition that could not be expressed in the light of day; night was their day!" (pedro sinde in "Barros Basto, A Miragem Marrana", Alexandre Teixeira Mendes, Ladina, Porto, 2007
