Damn, that is seriously impressiveThat would be larger than the Pyramid of Giza. The Great Pyramid of Giza was 139m (482ft) which was the tallest structure in the world For 3800 years (until 1100 AD). If Wargaade Wall was 220m it would have taken the title of largest man-made structure from the Pyramid of Giza making it a crazy tourist attraction.
What was the wall even for? To enclose some sort of compound? There's still so much we don't know about our ancestors.
