UNESCO specifies heritage as the cultural legacy which we receive from the past, live in the present and pass on to future generations. Cultural heritage is not limited to monuments and collections of objects. It is also comprised of living expressions inherited from our ancestors, such as oral traditions, performing arts, social manners, rituals, festive events, knowledge and practices related to nature and the universe, including knowledge and techniques linked to traditional crafts.
For this reason, it can be classified to tangible cultural heritage (movable, immobile and underwater) and intangible cultural heritage (ICH) embedded into cultural, and natural heritage artefacts, sites or monuments. Tangible forms of heritage may include: immovable cultural heritage, such as monuments, buildings, archaeological sites, movable cultural heritage such as paintings, sculptures, coins, manuscripts; and underwater cultural heritage, such as shipwrecks, underwater ruins and cities. Intangible forms of heritage, may include: oral traditions, performing arts, rituals, traditional craftsmanship practices. Despite its fragility, intangible cultural heritage or living heritage is an important factor in maintaining cultural diversity (Bocconi Univ., 2020: notes).
Finally, natural heritage includes natural sites with cultural aspects such as cultural landscapes, physical, biological or geological formations (Bocconi Univ., 2020).
Technology plays a cardinal role for the evolution of cultural heritage. Hence, the use of ICH has helped and facilitated the discovery of new masterpieces and forms of art, such as: 3D creations, image scanning, High Definition (HD) reproductions as well as online access (Bocconi Univ., 2020).
