Input: Only one in fivew Croatian Jews survived the Holocaust of World War II . Between 1948 and 1952 , nearly one half of the surviving members of Jewish Community of Zagreb opted for emigration to Israel , and the community dropped to one @-@ tenth of its pre @-@ war membership . The Yugoslav communist regime nationalized virtually all real estate owned by the Jewish Community of Zagreb , including the plot in Praska Street . All this , combined with the new regime 's general hostility toward religion , made reconstruction of the synagogue nearly impossible . After World War II , the vacant site of the former synagogue was used as a makeshift volleyball court . The volleyball court made way for a prefabricated department store building , constructed in 1959 . The department store was completely destroyed in a fire on December 31 , 1980 , and was subsequently dismantled . Despite some earlier ideas about a permanent department store building on the same spot , and a 1977 architecture competition for its design , no construction took place . Instead , the parcel was turned into a parking lot , which it remains to this day . After 1986 , the Jewish Community of Zagreb began to consider a Jewish cultural center and a memorial synagogue . Two architects , Branko Silain and Boris Morsan , both of whom participated in the failed 1977 department store competition , came forward on their own accord and contributed their ideas for a new Jewish center in Praska Street . Silain 's vision was ultimately not accepted by the Jewish community ; instead , plans were being made for the construction of the cultural center and a synagogue , following an international architecture competition . However , despite support for the project both within Yugoslavia and abroad , the issuance of necessary permits was either stalled or denied by the municipal government . The project was not developed . fill in the blank : Only one in five Croatian Jews survived the Holocaust of __________________ War II .
