Build The Wall!
On the 30th anniversary of the fall of the Berlin Wall, Katy Long asks why political leaders are celebrating the occasion while building new border walls of their own.
From the United States, where 'build the wall' has become a symbol of the Trump presidency, to Norway, India and South Africa, dozens of walls have gone up since 1989, with many more being built, planned or imagined. In this programme, Katy tells the modern history of border walls to ask why they are being built, and why now, when new virtual technologies increasingly offer alternatives to concrete barriers.
