Bomb discovery common across Germany

Uncovering World War Two bombs is relatively common in Germany. In April 2019 a 250kg bomb was found near Frankfurt, the detonation of which caused a massive water fountain.

Also in April, the discovery of a bomb on the outskirts of Cologne led to significant disruption and delays.

At the end of March, 10,000 people were evacuated in Rostock after a WWII bomb discovery.

In February, over 4,000 residents in Essen were evacuated when an American bomb was found during construction work.

Just a couple of weeks later, a 250 kilogram bomb was found in the centre of Nuremberg during construction work, leading to the evacuation of 8,000 residents.

The largest post-war evacuation happened in September 2017, following the discovery of a bomb weighing several tons near the Frankfurt university campus. More than 60,000 people were affected.
