The main European strategy concerning cultural heritage is the so-called Recommendation of the Committee of Ministers to member States on the European Cultural Heritage Strategy for the 21st century or short “Strategy 21” that was adopted in 2017.
It tackles the topics of protecting and promoting cultural heritage in general and not specifically archaeological heritage or even more precisely archaeological parks. It does, however, give some general recommendations in use and management of cultural heritage. Strategy 21 has three main components linked to a series of challenges (strategic goals) and recommendations on how to address the challenges and achieve goals. For the analysis of strategic challenges, a special analysis tool was used – SWOT analysis – a tool that inspects internal strengths and weaknesses and external opportunities and threats of the studied entities and helps to establish the direction and scope of the strategy.
