30#

Walked past this hundreds of times and never noticed the number before.
The wall is over 100yrs old, so the person who did it is long gone.
Wonder who it was and why they did it?
Did the bricklayer notice when they built the wall?

Did they bricklayer do it when he built the wall? Interesting find.

@jamibann having had a summer job making bricks, I reckon it was done while the brick was still soft, before firing. It’d be quite hard to carve it so cleanly into a baked brick.
