What Is a UNESCO World Heritage Site?

UNESCO’s Role in Protecting Cultural and Natural Sites

UNESCO (the United Nations Educational, Scientific and Cultural Organization) works to identify and protect places around the world that hold outstanding cultural or natural value for humanity. These are known as World Heritage Sites.

To be included on the World Heritage List, a site must meet at least one of ten selection criteria—ranging from representing a masterpiece of human creative genius to containing exceptional natural beauty or geological significance. The nomination process is detailed and includes evaluation by expert advisory bodies.

There are three types of UNESCO World Heritage Sites:

  • Cultural: Human-made landmarks such as cities, buildings, and archaeological sites.
  • Natural: Landscapes or ecosystems with scientific, conservation, or aesthetic importance.
  • Mixed: Sites that contain both cultural and natural value.

Why Italy Has So Many UNESCO Sites

Italy plays a central role in world history, particularly in the development of art, architecture, urban planning, and religious tradition. It was the heart of the Roman Empire, a cradle of the Renaissance, and home to centuries of innovation in design and engineering.

As of 2025, Italy has 60 UNESCO World Heritage Sites, making it the country with the most listings in the world. These include ancient cities, historic centers, churches, palaces, coastal landscapes, and mountain ranges.

You can find the full, updated list on the official UNESCO website.
