I just heard this on the news here, it’s terrible. Holding on to cultural objects is of utmost importance, and preserving the achievements of predecessors is not only respectful, it’s also educational. Not to mention art objects are one-of-a-kind and therefore irreplacable. Saying “everything gets lost sooner or later anyway” is too easy; might as not do anything as a species then.
‘Fire’ is so definite, it just completely destroys everything that’s gets grabbed by the flames. The building will sadly be lost by the looks of things, but I hope the cases objects were protected by, and the vaults some would have been stored in, proved to be just enough protection for items to be salvagable. Even if for only some.
