请翻译以下英文内容为简体中文： The Great Wall of China is one of the most impressive architectural feats in the world. It was built between 220 BC and the Ming Dynasty (1368-1644 AD) to keep out invading barbarian nomads from the north. The Great Wall stretches over 13,000 miles and is made up of many different sections, some of which are in ruins while others have been restored and are popular tourist attractions. Climbing the Great Wall can be a challenging but rewarding experience, providing spectacular views of the Chinese countryside.
