I may have the wrong city but I think I remember reading about this in National Geographic when it happened. Lots of pictures of damaged art and high water marks. Back then it was just a bad flood now its climate change and we all are going to die. Gave up on Nat Geographic about 20 years ago when everything was global warming and a species a day was going extinct according to them.
Most likely it was Venice with its canal system.
Both Florence and Venice, 1966. Marks are "acqua alta."
From the 1970’s on we’ve had overpopulation, new ice age, acid rain, ozone hole, global warming and climate change. None of them real. All of them designed to give power to the left (who are all Sun deniers).
