This is a poor picture but a brilliant view.  Taken from Fenchurch Street, on the left is the recently-completed Willis Building.  The most popular view of this block is looking into the three curves that face the Lloyds Building. From this point of view, the convex external wall is visible and one of the roof gardens.  In the centre is the just-completed Heron Tower and to the right, 30 St Mary Axe.  Immediately behind the photographer is the Lloyds Register – a spot worth returning to in good weather.
