History

Jews Survived WWII by living in a Cave,  For almost two years, the Stermer family lived with several other Jews in underground caves in the Ukraine to avoid being captured by Nazis, a little-known yet incredible tale. The Stermer family and several others spent 344 consecutive days living in what is known as Priest's Grotto, a "massive underground sanctuary," in the Ukraine during World War II, Brian Handwerk reported for National Geographic News.
