Central Frankfurt looked like a ghost town after almost 60,000 people were evacuated, forced to leave their homes ahead of the operation in the German city.
Allied warplanes bombarded Germany with more than 1.7 million tons of of bombs throughout the war, according to Reuters. The city set up a temporary shelter at Frankfurt's trade fair site, serving bananas and beverages.
About 60,000 people had to leave their homes after being warned that an uncontrolled explosion could flatten a city block. On Sunday, police cordoned off the 1-square mile evacuation area. German officials estimate 15 percent of the bombs failed to explode, some burrowing six meters (yards) deep.

The massive operation began at dawn, as homes and buildings within a 1.5-kilometre radius of the site were ordered cleared by 6 a.m. But residents who drove couldn't return until patients who were evacuated from two area hospitals had made it back.
Three police explosives experts in Goettingen were killed in 2010 while preparing to defuse a 450 kg bomb.
