Overview
The new Jewish Synagogue was completed in 1902 after the previous one, built out of wood, burned down in the Great Fire of 1856. It was a magnificent stone building with two tall turrets, stained glass, and original artwork painted by local artist Aba Fenichel.
According to Shoah survivor Jack Sittsamer, the building seen on the left of the synagogue was the Beit Midrash, and the building on the right was the Kloyz. Jack Sittsamer says that his family attended the Beit Midrash for prayer, rather than the main synagogue which “was for the wealthy, less observant Jews” [this has not been verified by other sources]. He says that his mother’s family (Montag-Kirschenbaum) attended the Kloyz for prayer.
Destruction
At the outbreak of World War II, the German Army invaded Mielec and one week later, on Erev Rosh Hashanah, locked Jews inside the synagogue, poured gasoline on it, and lit it on fire. See the Shoah page for more information on this horrific event.

Memorial
Currently all that is left of the new Jewish Synagogue of Mielec is a stone memorial near its prior location, and one torah scroll that is part of the Oborski Museum collection.
