Is China the one with the Great Wall or is that the US?

The Great Wall of China is a series of walls and fortifications that were built along the northern borders of China to protect the Chinese states and empires from the raids and invasions of various nomadic groups. The Great Wall is located entirely in China and is considered one of the Seven Wonders of the Medieval World.

The wall has a total length of over 13,000 miles, and it was built over the course of several centuries, with construction starting in the 7th century BC and continuing until the 16th century AD. The wall was constructed using a variety of materials, including brick, tamped earth, stone, and wood.

Although the Great Wall was originally built as a defensive structure, it also served as a symbol of Chinese strength and unity, as well as a means of regulating trade and immigration. Today, the Great Wall is a popular tourist attraction and is visited by millions of people each year.
