At my post in Weekend Reflections, I refer to Carrick Hill and that more information would be coming.
(That post was taken from the bottom right hand corner of this picture)
You can read about this wonderful building at http://www.carrickhill.sa.gov.au/history.html
The images in the top left and bottom right are of a Pleached Pear Arbor
(which I'd not heard of before) - see below for an explanation of this term.
Sorry, you'll need to click on this image to enlarge it (my blogging skills aren't yet sufficiently developed to use a better method !) - but it is worth reading.
