UNESCO World Heritage Sites are places recognized for their cultural or natural importance. The program began in 1972 and is managed by an international organization called UNESCO. Sites are selected because they have special value to the world.

Examples include the Great Barrier Reef in Australia, the pyramids of Egypt, and Machu Picchu in Peru. There are over 1,000 sites across more than 160 countries. These locations can include forests, cities, monuments, and landscapes.

World Heritage Sites are protected and monitored to preserve them. Rules are often put in place to limit damage and manage visitors.
