Great Wall of China

The Great Wall of China is one of the longest manmade structures in the world. Stretching more than 21,000 kilometres and dating back thousands of years, the ancient marvel in today's picture is a series of fortifications spanning rugged mountains, valleys and deserts. Although it was originally conceived in the 3rd century BCE, some of its most famous sections were built during the Ming dynasty between the 14th and 17th centuries CE. This UNESCO World Heritage Site showcases advanced ancient engineering and remains a symbol of Chinese history and culture. Featuring steep trenches and watchtowers, parts of it were designed to keep invaders at bay. Hiking the Great Wall offers a unique glimpse into this historical landmark. The experience varies from well-preserved sections like Mutianyu to wild, unrestored parts such as Jiankou. Some steps are so high, they're more like steps on a ladder! The Great Wall of China isn't just a wall, but a symbol of perseverance and strength.
