What would the Berlin Wall look like - if it was rebuilt in Britain?
Well, like this perhaps -
An artist called Mark Gubb has spent the week with timber, cement and fake barbed wire for an unusual performance on Saturday. It's a re- enactment of the death of a teenager who tried to cross the wall exactly 45 years ago today.
Peter Fechter was shot by East German border guards and left to die where he fell, on the East side of the wall.
On PM tonight Nigel Wrench hears from the artist -- that's him in the foreground at a first rehearsal -- and we'll tell you why he asked us to keep the location a secret. And why do this at all?
