We chose to deal with the castles and the people that live in walled cities and cities with castles (history, traditions, nations, religions, habits, etc). The students of the two countries (Greece and Romania) will focus on our common cultural heritage and on the need to preserve it, especially in a time when emblems of ancient history are being destroyed with barbarian actions. We will focus on the past, but also on the present, comparing traditions, habits and lifestyles and above all on our common future and the challenges we will have to cope with.
