Boris Bike Bollard Island...

Welcome to a local council 'Boris Bike Bollard Island'. I am always surprised at the level councils will go to adding not just bollards to protect a line of bikes but then creating custom built designed islands to then place the bollard upon.
If in an age of austerity we seek/wish to save money then a bollard with no island would do exactly the same job.
A huge thank you to Peter Elwell who sent me a photograph via email (below) of this superb cannon #guestbollard found at the exit of Dray Walk on Brick Lane.
Look at the body of the bollard/cannon tapering inwards until we reach the muzzle of the cannon/bollard where it flares outwards. The bollard/cannon has been capped off but with a small cone shape object and not the usual cannon ball top finish.
