The Great Polish Map of Scotland

The Great Polish Map of Scotland is a large three-dimensional, outdoor concrete scale model of Scotland, located in the grounds of the Barony Castle Hotel, outside the village of Eddleston near Peebles in the Scottish Borders. It is also known as the Mapa Scotland or the Barony Map. The brainchild of Polish war veteran Jan Tomasik, it was built between 1974 and 1979 and is claimed to be the world's largest terrain relief model. The sculpture is a category B listed building, and has been restored by a group calling itself Mapa Scotland.
