Must Come Down

You know what they say... What goes up, must come down. This week, we get into the conservation and decommissioning of public art. Starring this week are Recumbent Horse (from Episode 2) and the Paolozzi Mosaics. You'll also hear stories about Greyfriars Bobby and Serra's controversial Tilted Arch. Nothing lasts forever, so how do we keep public sculpture around for so long?
