The originality of the Belfort presentation lies in linking puppets to the notion of intangible heritage, also known as "living heritage". This term has the advantage of underlining the fact that heritage is played out in the present and is passed on. With this in mind, UNESCO has opened a register of best practices for safeguarding this type of heritage. Museums naturally have a role to play in promoting and transmitting this heritage. Thanks to a partnership with the Théâtre de Marionnettes de Belfort and a space dedicated to handling and demonstrating puppets at the heart of the exhibition, the Museums of Belfort intend to give visibility to this little-known heritage and work, in its own way, towards its transmission and therefore its conservation.
