During World War II 84% of Warsaw was destroyed which can be observed in the video below. Dramatic snaps in colour show the centre of the city, including Śródmieście, Old Town and meaningful empty space after the Jewish Ghetto. The photos were taken by Henry N. Cobb who as part of the group of American architects visited England, Czechoslovakia and Poland in the summer 1947. Furthermore, some of the snaps compare places before and after World War II. The last snap reveals the image of Warsaw today, 66 years after the War.
