Stop! History ahead!

We've passed by so often and never stopped look - until today. An old church, by Australian standards, whose building commenced in 1842; now that's even older than I am. Some good stonework and beautifully maintained, it is on the outskirts of Lithgow, and Presbyterian. I'm going to look a bit further and see if there's any more detail on it - quite a lot is known anout its general location, Bowenfels.
