The holes being 20 to 25 mm in diameter.
Recently I decided to look at the other walls and found holes on the East and South facing walls:
There are scores of holes, mainly above head height and much smaller at about 10mm diameter. They give much more the appearance of being the homes of masonry bees. I doubt I will ever find out for certain what made those larger holes on the North side.
To quote Toyah: "It's a Mystery"
A mystery indeed. I suspect someone will know the answer.
ReplyDeleteWorth keeping an eye on those masonry holes later in the year as the mining bees may return :) A fascinating mystery :)
