The Mayor of Oslo, Fabian Stang, has overseen the annual felling of a Norway spruce tree for Trafalgar Square. The tree is typically a 50- to 60-year-old tree, over 20 metres tall.
After the tree is cut, it is shipped to London by sea.
At the base of the tree stands a plaque, bearing the words:
This tree is given by the city of Oslo as a token of Norwegian gratitude to the people of London for their assistance during the years 1940-45. A tree has been given annually since 1947.
