While the definition of cultural heritage can change from nation to nation, 1973 legislation from the United Nations Educational, Scientific, and Cultural Organization (UNESCO) defined the different aspects of cultural heritage as follows:
Tangible cultural heritage
movable cultural heritage (paintings, sculptures, coins, manuscripts)
immovable cultural heritage (monuments, archaeological sites, etc.)
underwater cultural heritage (shipwrecks, underwater ruins and cities)
Intangible cultural heritage: oral traditions, performing arts, rituals
Natural heritage: natural sites with cultural aspects such as cultural landscapes, physical, biological or geological formations
Heritage in the event of armed conflict
