The Great Wall of India

Though less extensive than China's, is the world's second largest.  

This 36-kilometer-long, formidable fortification encompasses numerous temples and artworks.  

Constructed in the 15th century by Rana Kumbha, this UNESCO World Heritage Site showcases Rajasthan's military architecture and rich history.  

The Kumbhalgarh Fortress, situated within the Aravalli Mountains, serves as its centerpiece.
