A bicycle courier rests at lunchtime in Finsbury Circus which is one of the most prominent of the City's open spaces. What is unique about this open space is that it is elliptical. The buildings on each side are formed by a pair of graceful curved terraces and typically of the City, house the offices of banks, insurers and petro-chemical companies. Until last week, I used to work there but from Monday I’ll be working in Bishopsgate which is just round the corner.
