There are many traditional patterns of Scottish dry stone walling.
Here is one - 'The MacQuarry Wall'
The wall style transitions upwards into tightly coursed rows of round stones and has a tidy belt of brown copes along the top.
The reddish stone all comes from a special quarry.
Sadly, the stone supply at that quarry has been completely depleated and there are no more walls being kilt like this.
