Under the end of the Cold War and the advance of globalisation,the role played by the EU's borders and the symbolism behind them are undergoing profound changes.While the era of globalisation once heralded the blurring of borders,today,in the face of an increasingly complex and volatile international environ-ment,national borders continue to be re-emphasised as key barriers to safeguarding the interests of member states,even within the increasingly integrated European Union(EU).Particularly in response to non-traditional security threats posed by neo-nationalism,the European refugee crisis and terrorist activi-ties,the awareness of the EU and its member States of the need for increased re-borderisation has become par-ticularly pronounced,causing the trend towards re-borderisation to reach an unprecedented intensity in re-cent years.
