I with you LLL I've spent most of the weekend noseying around places that have intrigued me for years. I went around the NI parliment and castle offices aswell as a few local stately homes and a lighthouse. A fantastic way to spend the weekend and the weather was good to. My wife enjoyed it to and already making plans for next year.
Keep an eye out for it next year fellas

703,961 excluding any piers including standard bricks and joints, and a solid wall same thickness top to bottom. Presuming the area quoted is that of inside the walling.
I think....

i made it about half a million
20,000m being the area
square root an divide bt pi to get 45M radius
2 pi R to get circumference
= 282m
times 360 bricks per metre
=101823
times 3.5 m high (may be 4 hard to tell)
=356,387 bricks
i wonder what the prices were like in the old days?
i know this 1 walled garden had 55 gardeners full time before the war,and 1 head gardener who was the only man allowed to smoke at work

I didnt realise it was round??
I did square root of 20,000 to get one wall size 141.42m x 4 = 565.69 linear metres.
565.69 x 3.5m = 1979.89 face metres.
.675m (thickness) divide by 112.5mm = 6 bricks thick.
59.26 bricks to a face metre.
Face metres 1979.89 x 59.26 = 117328.28 face bricks
multiply by 6 bricks thick = 703,967 (i didnt round anything off this time, those 6 bricks make all the difference!!!!)

60 bricks per metre on 100 mm BWK
120 on 9"
