What I learnt from retracing the iron curtain

Just before the pandemic, I spent several months travelling through Europe from the north of Norway to Istanbul and beyond to Azerbaijan. I saw unforgettable sights: the endless daylight of the Arctic summer; the vast Hammershus castle on the Danish island of Bornholm; Vienna’s ornate Prunksaal library; and the sandy beaches of Corfu.

But the focus of my journey was precisely those things that most travellers to these places often ignore. I was following the route of the Iron Curtain. My aim was to visit every part of that old great divide, all the places where NATO once abutted the Warsaw Pact, where overwhelming military might stood constantly primed for apocalypse.

I wanted to understand how this epochal division had operated in practice, what it had meant to the people who lived nearby, and how its legacy – physical, political and emotional – has continued to make itself felt in the present.
