Lamp post?

They appear in odd places.
Sewers are vented, often simply by perforated manhole covers. In victorian times, cast-iron posts, similar to this, were placed, 25-30 feet high, with open-vented tops. These, warmed by the sun, would provide an updraught which drew in air at other points and flushed the system free of dangerous methane, or "firedamp" which was the silent, invisible killer of miners and sewermen.

have a look at this...google didn't go up Moriah hill as far as they could, but this is a view up it from the road by the park in Risca. the "bollard" is on the rhs of the path, about 10 feet before it goes over the railway
