The Great Wall Map Revealed | Cultural Compass Blaeu’s great wall map
(GWM) is one of the largest ever published, measuring 2995 x 2043 mm,
nearly 10 x 7 feet from edge to edge. Another copy was incorporated
into an enormous atlas, often cited as the largest atlas in the world, made for Charles II but still the map had to be cropped to fit. Presumably the atlas did not accompany the king on road trips.
