From the Top of the Town

This rather abstract image was taken at the highest point of our town (there is a clue there).

If you are lying down, you may see more clearly what this is.

Another clue: I actually blipped this two years ago.

Extra will be added tomorrow to clarify.
Extra has now been added.
It is the external staircase on the water tower at the top of the town.  Two further water tanks at a lower level.  All run by Scottish Water.
