The Great Polish Map of Scotland is located on the grounds of the Barony Castle Hotel. Found near the borders town of Eddleston, just north of Peebles, or a 50 minute drive from Edinburgh. We visited it on our way north from England, which didn’t take use too much out of our way. It is free to visit so a must visit for all map enthusiasts in Scotland or Northern England.
Built between 1974 and 1979 to a scale of 1:10000 it is truly impressive to behold (50 m x 40 m on the ground). It is the largest known physical representation of a country and the largest outdoor relief map in the world (signpost at the map). Envisioned by Jan Tomasik, a Polish sergeant. He had been station in Galashiels during WW2, and added the Hotel Black Barony to his holdings in 1968, providing the map a location. The map itself was built in stages over a number of years, with Polish exchange students providing some of the manpower required.
The map is now maintained by Mapa Scotland. A charity who are now working on restoring the map. Parts of it are currently in poor condition, but overall it is an impressive site.
Also the grounds of the hotel in general are really beautiful, with a small glen running through the site, if visiting the Scottish Borders it would make a great place to stay: Barony Castle Hotel.
