Structures made during ancient times that were truly remarkable. They include :- Great Pyramid of Giza.- Hanging Gardens of Babylon.- Lighthouse of Alexandria.- Mausoleum at Harlicanassus.- Statue of Zeus at Olympia.- Temple of Artemis at Ephesus.- Colussus of Rhodes.But among these ancient wonders only the Great Pyramid of Giza still exists today. The rest having been destroyed or lost with time.So a list of the New seven wonders of the world was made and released  in 2007. This list includes:- Great Wall of China: First built in the 7th century, the great wall is made from stone, bricks and wood.
