When I was in Amsterdam I came across a book from a street photographer Bernard Eilers of photos he took from 1896 to 1936. I looked at the images and recognized most of places. The wonderful thing about a lot of major European cities is that they have remained unchanged for most of the time. I revisited the locations in the photos and put the original beside it.
One the left of the images is the original taken by Eilers.
This is in the middle of the red light district. In the right image in the left windows there working girls. I had to be careful not to have my camera out since they don’t appreciate being photographed.
Again right in the middle of the red light district. In the background is the Oude Kerk (Old Church). Sailors would frequent the red light district then visit the church for forgiveness and then ship out the next day. At one point you could visit the church and confess your sins before you were about to commit them, and off course payment was involved.
