Other lists

Throughout the ages, similar lists were made. For example, during the 19th and the 20th centuries, many scientists tried to enlist the Wonders of the Middle Ages (the Great Wall of China, Hagia Sophia, Ely Cathedral, Cluny abbey...) More recently, lists were made in order to promote man-made works (the Channel tunnel, towers, bridges...) We've got also the Seven Wonders of the underwater world, of Canada, of Russia...
