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.
East of the River Irthing, the wall was made from squared stone and measured 3 metres (9.8 feet) wide and 5 to 6 metres (16 to 20 feet) high, while west of the river the wall was originally made from turf and measured 6 metres (20 feet) wide and 3.5 metres (11 feet) high; it was later rebuilt in stone.
