The UK pavilion at Expo 2010, colloquially known as the Seed Cathedral, was a sculpture structure built by a nine member conglomeration of British business and government resources directed by designer Thomas Heatherwick. It referenced the race to save seeds from round the world in banks, and housed 60,000 plant seeds at the end of acrylic rods, held in place by geometrically-cut holes with the rods inserted therein.
The structure stood where it was built, at a cost of £25 million, in Shanghai for the 2010 World Expo.
The cathedral's architecture was an elaboration of Heatherwick's 2003 work of the Sitooterie II in Essex, United Kingdom.
The cathedral has now been dismantled, with some rods donated to schools, some donated to the World Expo Museum and some being auctioned for charity
