When the Avenues area of Hull was built they were lined with trees which, over the years, grew and grew. Now the soil of Hull is really just glorified play-doh. Big trees and houses built on clay don't mix very well, so the big trees have got to come down and be replaced by less troublesome varieties. Rather than just removing them completely the stumps have been carved into various sculptures. The local church is called St Cuthbert's so I guess that explains why we have a Lindisfarne theme.
