Warsaw's Old Town is a fake — painstakingly rebuilt from rubble and old photographs after 1945. It's also a UNESCO World Heritage Site. I take you through the reconstruction story: how it was done, what was changed, and what this says about how cities construct identity.

The Palace of Culture and Science was a 'gift' from Stalin to Poland — 237 metres of Soviet ambition in the centre of Warsaw. I'll take you inside, up to the viewing platform, and through the 3,000-room interior including a Soviet-era cinema still showing films.
