The image adopted as a summary, and at the same time as a source of inspiration for a museum conceived as a place for discussion and dialogue, is that of "tikkun". Referring to the concept of Lurianic creation and redemption, it was first given a predominant role in the light, very matter of the architectural structure; what might be called the "qelippah" building material, fails to contain such light "cracking" as the vessels of the master of Safed. This mixture of matter and light leads, naturally, to the symbolic dimension of tikkun, as recomposition of the fragments; this perspective is developed at different levels, first-level center. The National Museum of Italian Judaism and the Holocaust is, in fact, a valuable opportunity for the restructuring of the fracture history represented by the tragic events of the twentieth century. Tear contrasts thus the suture, a shift made possible thanks to the memory of the past; from a cultural point of view, are recomposed in one place the peculiarities of the rich tradition of Italian Jewry here are told through the ages, and related forms of social, cultural, religious and linguistic minorities. Every single object or reference to a particular religious or cultural expression, multiplies so their values, giving an account of its complexity and ability to renew its meaning, first to compose himself in the comparison between the different visitors; the narrative dimension is developed thus far beyond the walls / doors of the museum, in line with a clear conception of the museum and with the inspiration that animates the entire project.
