I wonder what the sources of the maps are. They seem most plentiful around the Netherlands amd Belgium. Also, the map for Stockholm had what looked like handwritten Dutch text om it.

Thanks!

I also noticed that the search is broken

That works a lot better, especially if there's nothing in your area.

It's really interesting to see how far off these old charts are when overlaid on modern GIS data, but still pretty impressive for the time.
