I am a hedgelayer, and drystone waller based in North Yorkshire. There are also numerous pictures of walls and hedges taken in the the British Isles and Europe.
This was definitely 'before'. Didn't look forward to this job as some of the stones were on the large size and I had to do a lot of digging to recover stones which had fallen into the small gully beside the wall.
But I managed and am quite pleased with the job - I even found enough tops which I thought might be hard to come by.
