hollow
Katie Paterson and Zeller & Moye’s public artwork, Hollow, is made out of 10,000 samples of different tree species and was unveiled in Bristol in early May. The BBC followed Katie over a ten-month period as she assembled the wood collection and created the artwork. Sourced from all around the world, her samples include the oldest tree in the world, a tree that survived a nuclear blast and many trees that are now extinct.
