The Greek historian Herodotus claimed that Babylon surpasses in wonder any city in the known world and specifically praised the walls which he said were 56 miles (90 kilometres) long, 80 feet (24 metres) thick, and 320 feet (97 metres) high.
The Wall is a massive barrier of mostly ice stretching across the northern border of the Seven Kingdoms, separating it from the wild lands beyond. The Wall is one hundred leagues long (three hundred miles) and reaches over seven hundred feet at his highest point, although some foundation blocks in hilly regions, such as near Greyguard, send it nine hundred feet in the air.
