Dancing, Singing Bollards...
Welcome to Regent's Park Road and the junction of Gloucester Avenue where I found these rather dandy stone/concrete bollards complete with 'ears' eyelets and even rusting padlock (see bottom picture).The bollards appear to be made of concrete and are octagonal in shape which then morphs into a domed /semi-circular finish. The 'ears' eyelets are obviously there because chains were used to link each bollard and create/mark the border of Cecil Sharp House which just happens to be home of the 'English Folk Dance and Song Society' which just so happens to be a point (or two) on the 'Knowledge of London' (exam that all London taxi-cab drivers have to pass).
See sign above...
Take a close look at the picture (top) and don't just admire the beautiful bollard but also note the lines/angles and conflicting symmetry of the wall/brickwork adjacent to the bollards and the pavement.
