I have played with OpenStreetMap lately, and it has significantly improved since I had last checked it a few years ago. The fact that any map can be exported as a pdf file, and that you can fix details on the map is making it much more useful than Google Maps for some of my projects.
On September 15, 1947, Gorizia was incorporated into Italy again, and a new border was drawn (or literally painted) with Yugoslavia. I always find old footage fascinating (click the picture to go to the British Pathé site).
The border is still there but there are no checkpoints and anybody can freely cross it.
We are working on some projects which should contribute to make these borders even less relevant.
