Today the string of palazzi that line the south side of the Arno River just west of the Ponte Vecchio looks like the picture below. Pay special note to surviving bellower of the church San Jacopo sopr’ Arno in the foreground.
And now here’s a vintage photo of the same area, with a string of older (much) palazzi.

In comparing the 2 photographs you can see that the palazzi have been replaced. The entire area was destroyed by German explosives in 1944 as they were being driven out of Florence by the Allied Forces. The newer structures are about 75 years old now.
This church, San Jacopo sopr’ Arno, is very interesting as well:
