THE BULGARIAN WRITTEN HERITAGE AS A CULTURAL RESOURCE AND A DRIVER OF SUSTAINABLE TOURISM

The Bulgarian written cultural heritage includes unique manuscripts, medieval literary monuments and archival funds, testifying to the spiritual and intellectual development of the Bulgarian people. This heritage not only reflects the cultural identity of the nation, but also provides a platform for the development of cultural tourism with a long-term sustainable effect. This article explores the Bulgarian written heritage not only as a national cultural treasure, but also as a strategic resource for the development of sustainable cultural tourism. Manuscript books and documents can be integrated into the tourism product through museums, libraries, archives, thematic routes and digital platforms. Good practices, the potential for cultural diplomacy and the contribution to local development are analyzed. Special attention is paid to the interrelationship between written cultural heritage and sustainable development, implemented through its preservation, educational initiatives and active community participation. The article focuses on the historical and cultural value of manuscripts and archives as factors determining the unique role of Bulgaria in European civilization. The importance of the preservation and restoration of manuscript and archival heritage is emphasized, while at the same time seeking a sustainable balance between preserving its authenticity and ensuring public access. The deficit of well-trained specialists and funding is noted, as well as the need for a transdisciplinary approach, including cultural studies, archival studies, information technologies and tourism planning. Bulgarian written heritage has enormous potential to be a bridge between the past and the future, while simultaneously contributing to cultural self-awareness and economic development through sustainable tourism. The authors call for the strategic integration of written heritage into public and private cultural policies based on long-term thinking and preservation. A long-term and coordinated vision based on inter-institutional cooperation, innovation and educational practices is needed.
