I'm not sure about cultural, but the great wall is man made.
No. The Great Wall of China was made by men, therefore it is not a natural feature. The Grand Canyon was carved by the natural force of water, and is therefore a natural feature.

The Great Wall of China.
The Great Wall of China served as a natural protection for northern China, as it acted as a barrier against invading forces. Additionally, the Gobi Desert to the north provided a natural obstacle that deterred potential invaders.
