The concept of Intangible Cultural Heritage was born within UNESCO, and defined by an agreement in 2003.
Intangible heritage manifests itself primarily in the following:
- Oral traditions and expressions, including languages
- Performing arts: dance, theater, music, etc.
- Festive rites and events
- Knowledge and practices concerning nature and the world around us
- Savoir-faire involved in traditional crafts
UNESCO distinguishes cultural and natural heritage (buildings and landscapes) from Intangible Cultural Heritage.
