About this converter
Famous wall lengths run from 4.018 to 21,196.18 km here, which makes every fortification easy to compare. The Jerusalem Old City circuit measures 4.018 km, while the Great Wall system measures 21,196.18. That means one Great Wall equals 5,274 Jerusalems. Every figure on this page is an official length from UNESCO listings, heritage agencies and wall surveys. Long systems use total constructed length while city walls use standing circuit length, and rows state the method. The Great Wall figure covers all walls, trenches and natural barriers from the 2007 to 2012 survey. Jerusalem uses a precise 4,018 m survey against rounded 4.5 km listings.
