If you look at this large pointy thing, sitting by a bridge in London, what would you think it is?
a) Over priced art the the city of London commissioned to make the city look ‘deep’.
b) A monument to mothers everywhere who have spent centuries yelling out ‘Don’t run with pointy things in your hands!’
c) A monument to medieval England and some rather unpleasant goings-on.
d) A giant sun dial.
The answer is a AND c. It is a spike meant to commemorate the location where traitors heads would be left on a pike to rot. Charming.
