The final pit where we found the most natural profile.

“There I was digging a hole, hole in the ground so big and sort of round …

… Well, its not there now, because beneath it is a bloke in a bowler hat.”

Apologies for quoting that evergreen top twenty hit from Bernard Cribbins about a jobsworth inspecting holes, but it has been threading through my thoughts all today as I excavated 4 x 2.5m holes around Dunans today, and then filled them in.

What was the purpose of this seemingly pointless exercise? Well, apart from giving me the opportunity to sing like Mr. Cribbin all day? To ascertain what the castle stands on. The answer is mixed. At the front of the castle we have a layer of gravel, followed by medium-sized stones and then a sandy soil down to at least 2.75m. At the side of the castle, we have a topsoil of 50cm, a layer of compacted earth for the next metre and a half and then sopping wet grey clay, hardening to schist somewhere below 2.5 metres. The back is a tale of sopping wet Clay from top soil down, and then further out on the south lawn (if you can call it that – maybe swamp would be better … Well, after 50cm of sopping turf and soil we get a surprisingly dry compacted earth which at around 1.5m goes into grey clay. 50cms below that it turns into grey schist which defies the digger.

I think Steve and Rebecca, our structural engineers from David Narro Associates were encouraged by the last pit, but overall? We’ve got to wait and see!
