1. The Great Wall of China (China)
Some parts of this massive wall started being built over 2,500 years ago to consolidate and protect Chinese territories against nomadic groups. From then on, it grew into a complex series of fortification systems of immeasurable architectural and historical value.
It spans over 21 thousand kilometers (13 thousand miles) across the northern borders. This absolutely impressive dimension has given rise to a myth that the Great Wall could be seen from the moon. It can’t.
But you can see it and tread its most famous trails from your living room. The China Guide website designed an amazing online tour through the Great Wall of China, packed with historical facts and insightful information that you can check as you move along certain sections of the wall.
