As of late 2023, the global registry maintained by UNESCO spans 1,199 total sites across 168 state parties, encompassing 933 cultural sites, 227 natural sites, and 39 mixed properties.
Global Distribution of World Heritage Sites
The UNESCO World Heritage list divides recognized locations into three distinct categories: cultural sites tied to human history and ingenuity, natural areas featuring exceptional ecological or geological value, and mixed properties containing elements of both. Prominent examples featured on the roster include the Pyramids of Egypt, the Great Barrier Reef in Australia, the Galápagos Islands in Ecuador, the Taj Mahal in India, the Grand Canyon in the USA, and the Acropolis in Greece.

To secure a place on the official roster, a location must satisfy at least one of ten strict evaluation metrics established by UNESCO. These standards range from representing a masterpiece of human creative genius to containing superlative natural phenomena or areas of exceptional aesthetic importance.
