It's odd how differently countries treat their cultural heritage. Poland, for example, has published a lot of archival materials in public domain [1]. But this is not the case for Austrian state, which, I guess, owns large fraction of the maps on OP website (Austro-Hungarian Empire). They also charge large sums for using materials from their digital archives.
However I dug deeper into the history of these (bavarian) maps and suprisingly found that there are a lot more maps that built the basis of the military maps. And boy, they are uncannily accurate. And of course scattered among archives, survey offices and libraries.
I even managed to find a map with the exact locations of buildings that are still standing today. Manually georefercing them showed that they are often only a few centimeters off.
And to get back to this comment: I had a hard time finding a general map from the same area. And when i found it the office that held the records. They also didn't hold one map, but several maps that were made over the years. However they wwere extremly expensive and I was even bombarded with several limitations. E.g. if I'd publish it in a journal I MUST notify the office with details.
Parent comment is right, that they should be in the public domain, however some administrative bodies still believe that they should be guarded as state secrets, probably because these maps were the basis of tax registers and most of the land units on these maps are still the same 150 years later. Even though the same office publishes WMS data of todays situation for free on their website.

Here's the famous 18th century Cassini map of France (first modern triangulated map, three generations of Cassinis worked on it)
https://www.loc.gov/item/gm72002942/
The LoC graciously scanned and hosts this copy. Arcanum also sells it: https://maps.arcanum.com/en/map/europe-18century-firstsurvey...
You'll notice that the Arcanum map is scanned, tiled, and hosted as a modern web scrollable map.
Furthermore the site hosts a number of historical and modern maps that are all geographically indexed and can be overlaid.
And while the depicted Moldavia region joined others to create the modern day Romania, its eastern part, Basarabia, only managed to rejoin Romania for 20 years in the late 19th century, and 20 years in the early 20th century, before being annexed yet again, until it finally became the modern Republic of Moldova. In the process, 50% of the native Romanian population was purposefully displaced.
The side effects of this occupation are very much felt even today. Moldovans still struggle with their national identity. Politicians frequently engage in bike-shedding and love to stir up 'state language' controversy to detract from real economic issues, corruption and poverty. There's enormous Russian influence over the region and interests to keep the country busy being poor and in turmoil.
These days I fear that if Russia invades Ukraine, they won't stop at the border with the Republic of Moldova, they'll annex Basarabia like they did in 1812 and again in 1940, to restore the 'glorious' Russian empire of the 19th century.
How far into Ukraine do you think they would manage/are likely to go? Odessa oblast has some Russian ethics, but I'm not at all sure they are enough to allow for the kind of dynamics that took place further East.
And if Russia can't/doesn't want to hold Odessa, it will definitely not go as far as Basarabia.
Within Ukraine there's a decent divide between those who are pro Russian in the south and those who would like to retain the Ukrainian language and culture, mostly in the north, so it wouldn't surprise me if Russia manages to retain the southern part, but ends up having trouble with North-Western Ukraine.
That said, this isn't a game of Civ and I hope the Ukrainian people won't have to go through that horror.
I find the map of Greece being written in German (published in Vienna) amusing
Some interesting things in London
1) The railway line from Waterloo East to Waterloo main is still in place
2) No Tower Bridge
3) The Circle/District/Metropolitain lines are shown
4) The Olympia-ShepherdsBush-Hammersmith loop is shown
5) There's a farm north of Shepherds Bush (where White City and the 1908 Olympics were held shortly after)
6) London in the north generally stops around Zone 2
Was just looking at it before I returned here. Find word LONDON, to the right look for A100 next to St. Katherine's Pier.
221b is NE of the word, in Marleybone, between A41 and Regent's Park. Resolution too poor to see if the statue's there yet. https://osm.org/go/euu4Hniql
What are you on about with A100? The UK road numbering system was a post-war thing
A fascinating resource.

You can see how 'mixed up' things were in the Istria area as well, with lots of Italian names mixed up with Slavic ones.
