POLISH historians have created an unusual 3D film that documents the shocking sea of rubble that Warsaw became during World War II.

Jan Oldakowski, the director of the Warsaw Uprising Museum, said the film "City of Ruins" is meant for young people who do not realize the degree to which Poland's capital was destroyed from 1939-45.

"Young people do not understand what it means that Warsaw was in ruins; they think it was just a few collapsed houses," Oldakowski said in Warsaw yesterday. "Nor were we, at the museum, fully aware of what the city looked like."

The destruction was the result of bombings carried out by Nazi Germany, which invaded Poland in 1939 and occupied it for six years.
