409. The non-material heritage is also included in the effort to safeguard the national heritage and this is done in harmony with the international trends aimed at the protection of this type of heritage, considered as a national asset. For this purpose, the National Heritage Institute is responsible for the protection of the non-material national heritage (folklore and traditional knowledge). 410. The setting up of a Research Unit « History and Memory » at the University of Manouba contributes to this effort aimed at the protection of the national heritage. It is a new perception of historical phenomena by inscribing them not in absolute terms, but in relative terms and by reflecting on them in terms of tolerance. 411.

The preservation and consolidation of this referential constitutes a strategic priority axis in its cultural policy.
