Fun Fact about China: The Great Wall of China, one of the most iconic and impressive architectural wonders in the world, is not a single continuous wall but rather a series of walls and fortifications. These walls were built and rebuilt over several dynasties and time periods, stretching over approximately 13,170 miles (21,196 kilometers) across northern China.
This remarkable structure was constructed to protect China from invasions and raids by various nomadic groups and military incursions. Its construction started as early as the 7th century BC and continued for centuries, with some sections dating back over 2,000 years. The Great Wall of China is a testament to the ingenuity and determination of ancient Chinese civilizations and stands today as a UNESCO World Heritage site, attracting millions of visitors every year.
