Pont des Arts, but in the last 5-6 years the awful "love" locks absolutely ruined this Paris treasure. It was originally built in 1804 and was the first metal bridge built in Paris ,but due to bombardments during both WW and being rammed by a barge, it was closed and rebuilt to exact specifications. The love locks compromised the bridge and in 2014 it was closed and several sections of replaced with glass panels. A total of 45 tons of locks were removed. Today it's again the lovely bridge we all remember and love!
