How might Warsaw be subdued? wondered Adolf Hitler. "By stealing its cultural identity," said a German army officer, "by looting its art, burning its archives, and leveling its landmarks." Thus a near 1000 buildings were tagged for demolition by German architectural historians. Meanwhile, foreseeing the city's fate, Varsovian architectural professors and their students, in a perilous act of disobedience, documented their patrimony so it could be recreated—risking deportation to the concentration camps. The drawings were sent to a monastery outside the city to be kept within the crypts. When seeing this precious cache, the monks removed the bones of ancient holy men from their stone sarcophagi, so the blueprints would be doubly safe from errant bombs.
