Warsaw, Poland
Blown-up 1943
The Great Synagogue of Warsaw (Polish: Wielka Synagoga w Warszawie) was one of the grandest synagogues constructed in Poland in the 19th century. At the time of its opening in 1878, it was the largest Jewish house of worship in the world. It was blown up personally by the German SS-Gruppenführer Jürgen Stroop on May 16, 1943, in retaliation for the Warsaw Ghetto uprising. The painting is based on an uncredited postcard from Wikipedia.
So much of Warsaw was rebuilt but not this. Anon.
