Archaeological wonders are remarkable sites or artifacts that provide insight into past civilizations. Examples include the Pyramids of Giza, which showcase the engineering skills of ancient Egyptians, and the Machu Picchu, a stunning Incan city nestled in the Andes Mountains. These sites help us understand human history, culture, and technological advancements. Another significant archaeological wonder is the Great Wall of China, a massive structure built to protect against invasions. Additionally, the Terracotta Army in Xi'an, China, consists of thousands of life-sized clay soldiers buried with the first Emperor of China, Qin Shi Huang, to accompany him in the afterlife.
