You may like to show your own images that compare the past with the present. Two images or more will be necessary for the comparison. Exact or estimated dates will be useful. My suggestion is that there is at least 20 years between shots unless there has been a rapid change in the landscape/cityscape/subject matter.
I will start. Westminster Mill. Horton Kirby. Kent. UK. An age old mill and weir. The mill demolished and replaced by housing.
Taken from same viewpoint.
Original picture 1974.
New picture yesterday - September 2020.
I have no comment
