edit: the number I remembered was lower than the actual count.
The last time was some weeks ago, and the local press not only did features about the two experts defusing the bomb, but was welcoming them by their first name, as they were old acquaintances.
Also, when you get official permission to build the permission does not only include restrictions like maximum height etc., but also very clear directives in case munitions are found, including the correct phone number in the regional government.
Before the permission for the building I'm living in was issued they actually interviewed older neighbours, one of which claimed he remembers some bomb droppings on this lot. They cross-checked with aerial imagery from the 1940s and concluded there was low risk and permission could be granted.
