Unknown Stones - Foreshore.

We spotted another couple of 'unknown' boundary stones down by the foreshore the other day when we went to gawp at stranded warship HMS Diamond, becalmed at Telford Dock.

Firstly, on the Queen's Links we noticed this concrete marker which is inscribed:

?(defaced) M
No 3

Being concrete, this stone intrigues us. It's not like the other boundary markers around town and we've not seen any others like it, but that doesn't mean there aren't any. It doesn't appear on Aberdeen City Council's Sites and Monuments Pages, but here's its RCAHMS entry.

Then, on Links Road we spotted this granite marker which is inscribed 'ABD', and also sports an Ordnance Survey benchmark rivet. Of which more later.

Oddly, its RCAHMS entry says that "Nothing is now visible of this boundary stone". We beg to differ. Here it is:

There are probably many other stones like this one, the 25 inch Ordnance Survey of 1869 certainly shows a good few. Over the coming weeks and months, we'll see if we can find some more of them.
