In 1941 80% of Jonava's population was Jewish and town had seven synagogues.[1] However, only two synagogues remain, the Beit Medrash Hagadol Synagogue and the Synagogue of Merchants; and both are not in use. The Red Synagogue was the biggest and main synagogue in Jonava, located in front of remaining Beit Midrash Hagadol Synagogue. The Red Synagogue, and all other synagogues, were destroyed when Jonava was attacked by Nazi Germany.[2][3]
