The project is aimed at achieving sustainable development of the Center for Excellence "Heritage BG", created in the period 2018-2023 under project BG05M2OP001-1.001-0001 "Construction and Development of Center for Excellence "Heritage BG". To achieve sustainable development, three types of activities are planned: ⁃ scientific research, development activities and promotion of their results, ⁃ modernization and/or retrofitting of the already built infrastructure, ⁃ training and mobility of researchers. The main activities are divided into three groups: 1. effective interaction between science, knowledge transfer and new technologies, especially in the creative and recreational industries; 2. achieving efficiency through interdisciplinarity, shared knowledge and shared work as an integral part of the European scientific complex; 3. creation and sharing of new products and intellectual assets to significantly improve and expand the "science - business - economic benefits - social benefits" interaction. For the implementation of the activities, a business plan was developed, containing a detailed description, including of: - work packages; - modernization/re-equipment of 12 sites from the already available infrastructure. With its sustainable development, the CoE "Heritage BG" will additionally contribute to: - the training of a qualified workforce, - the preparation of teachers and researchers for the educational system and for the institutions of memory, - continuing training for young scientists and their involvement in R&D, - the development of new products and services based on ICT and new/improved knowledge about Bulgaria's heritage.
