What is the longest wall of the world?

  • Wall of India
  • Wall of Egypt
  • Wall of China
  • Wall of Afghanistan
Correct Answer: C. Wall of China

Detailed Explanation

The correct answer is the Great Wall of China.


The Great Wall of China is a series of fortifications built across the historical northern borders of ancient Chinese states and the Chinese Empire. It is widely recognized as the longest man-made structure ever built.


Construction and Purpose:


Construction of the wall began as early as the 7th century BC by individual states. These were later joined together by Qin Shi Huang (220–206 BC), the first Emperor of China.



  • Defense: Its primary purpose was to protect the Chinese states and empires against raids and invasions from various nomadic groups from the Eurasian Steppe (such as the Mongols).

  • Control: Beyond defense, it allowed for border controls, the imposition of duties on goods transported along the Silk Road, and the regulation of trade and immigration.


How Long is the Wall?


According to an archaeological survey by China's State Administration of Cultural Heritage, the total length of the wall, including all its branches and natural defensive barriers (like hills and rivers), is approximately 21,196 kilometers (13,171 miles).


Comparison of the Options:



  • Wall of India: While India has the Great Wall of Kumbhalgarh (the second-longest continuous wall in the world at 36km), it is significantly shorter than the Chinese wall.

  • Wall of Egypt: Egypt is famous for its pyramids and temples, but it does not have a "Great Wall" of global record-breaking length.

  • Wall of China: The correct answer, spanning thousands of miles across northern China.

  • Wall of Afghanistan: Afghanistan has historical walls (like those around Kabul), but none that rival the scale of the Great Wall.
