after I saw Joe's message I looked at the list of archives, https://www.sucho.org/archives

One that caught my eye was Lviv Interactive        https://lia.lvivcenter.org/#!/map/        Interactive map of Lviv
I had a rather horrid thought that we need good pictorial maps with background formation for cities like Mariupol which have undergone fierce bombardment, to show what the city was like before the present war.

btw, there is an "old town" in Warsaw, Poland a large part of which consists of buildings which are not that old but are a faithful reconstruction of buildings which were destroyed in WW2. Part of the old town section of Gdansk is likewise a postwar reconstruction.
