For travellers who want to experience some of the history and mystery of the ancient world, here is a list of cool destinations for your next holiday. Angkor Wat, Cambodia Built in the 12th century, Angkor Wat (meaning “capital monastery”) was a temple in the ancient Khmer capital city of Angkor. It is Cambodia’s best-known tourist attraction and is famed for its beautiful architecture and reliefs. You’ll need at least three days to fully discover the delights of this magnificent site. Machu Picchu, Peru Machu Picchu was built high in the Andes Mountains of South America by the Inca in the 15th century. Although well preserved its exact purpose is unknown. It is famous throughout the world not only for its incredible design but also for the natural beauty that surrounds it. Give yourself a week to explore this magnificent site. Stonehenge, England The entire Stonehenge site was constructed over thousands of years. But why and how it was built remains a mystery. As the weather can be pretty bleak in winter and the crowds huge in summer, we suggest autumn should be the best time to visit these monster rocks. Pompeii, Italy When Mount Vesuvius erupted in 79 A.D., Pompeii was buried under many layers of ash, preserving the city exactly as it was when the volcano erupted. Because so many objects were preserved, scientists and visitors are able to better understand daily life in the ancient Roman Empire. 小题1:Why may people want to visit Machu Picchu?
