When I was stationed at Ft. Riley, KS back in the 90’s the 74th EOD commander was a friend of mine. He told me they had been called out to remove some civil war era munitions from an attic at a residence just off post.

German WWII bombs are still being dug up in England, and Allied bombs are being regularly dug up in Germany. They just evacuated thousands from Frankfort a couple of days ago to defuse a WWII era bomb:
