Snow on the Great Wall, China

Step up your game. Great Wall of China

The Great Wall of China is, one of the longest manmade structures in the world. Stretching more than 20,900 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. 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. The Great Wall of China isn't just a wall, but a symbol of perseverance and strength.

Similarly, Kumbhalgarh, often called the 'Great Wall of India,' embodies its own history and enduring legacy. It is in the Aravalli Hills in the Rajsamand district of Rajasthan. Situated about 48 kilometres from Rajsamand city and 84 kilometres from Udaipur, this impressive structure was built in the 15th century by Rana Kumbha. The Kumbhalgarh Wall, one of the longest continuous walls in the world, stretches over 38 kilometres.
