Historical version 7 of Shepherd's Bush Roundabout (view current version)
Intersection between the A3220 to the north, Holland Park Avenue to the east, [Holland Road]? to the south and a road to the west which splits into the Uxbridge Road to the north side and Shepherd's Bush Green to the south side of [Shepherd's Bush Common]?.
It has a rather unusual piece of art in the middle of it which is a blue and clear plastic water tower - sponsored by Thames Water.
Addition: I think that this 'statue' is actually a barometer. The higher the water, the higher the pressure. Can anyone corroborate?
Edit: Don't take this as gospel, but I think it's a pressure-balancing tower; the height is chosen to match the water table somewhere like Harrow. I think it's part of the 'super ring main' around London, documented in the Kew Bridge Steam Museum (itself an old water pumping station).
I remember hearing something like that back when it opened a decade(?) ago. But then again, I've heard lots of people put forward the barometer theory since then, too. Help! -- Earle
