The "Great Wall of India" refers to the wall of Kumbhalgarh Fort in Rajasthan, the second-longest continuous wall in the world. Built in the 15th century by Rana Kumbha, it stretches 36 kilometers (22 miles) and is wide enough in some sections for eight horses to ride abreast. This UNESCO World Heritage Site encircles the fort and is also home to around 360 ancient temples.
