when you say gate pylons.... do you mean the big H gate entrances...
There was one at the front (facing train station) and one on the right(facing the boating pool)
I believe the one in the pic is the front one, the pic is taken at such an angle that the sea seems to go right past.
and it probaly does as it carries on down to the docks....
If the picture was in reverse then the Big Fish Roundabout thing would all be facing the other way, and that would seem odd...
just a thought...
