The next section, Barriers and connections, examines the dual nature of borders, the fact that they can be both physical and conceptual, constructed or physical barriers. Europe is central to ongoing debates over migration and human rights on the one hand and national sovereignty and protectionism on the other. It is seen as both a haven of human rights and a cruel fortress. Cultural events, sport, festivals and fairs aim to mirror an ideal society, helping to define the social, cultural, economic and private aspects of being European.
