Before the Nazi German invasion of Poland in 1939, almost every Polish town had a synagogue or a Jewish house of prayer of some kind.
The 1939 statistics recorded the total of 1,415 Jewish communities in the country just before the outbreak of war, each composed of at least 100 members (Gruber, 1995).
[1] The list of actives synagogues in Poland cannot possibly include the hundreds of synagogue buildings which still stand today in about 250 cities and towns across the country – seventy years after the Holocaust in Poland which claimed the lives of over 90% of Polish Jewry.
This isn't necessarily bad however, because the synagogues which remain empty are usually worse off due to lack of maintenance.
