One of the great pleasures of cycling round London is coming across works of art like this, unobtrusively mounted on a wall on a canal towpath, quietly brightening my day.
Entitled A World in Islington, the four mosaics illustrate the changing canal landscape over the 200 years or so since it was built. They were created in 2010 by pupils at the Hanover Primary School just behind the wall. Artists Carina Wyatt and Cathy Ludlow 'helped', as they say.
My favourite panel shows narrowboats being hauled by horses to the basin where they are being unloaded.
