Over the course of a weekend we were introduced to the basics of flint walling, the mortar mix used to hold the flints in place, selecting and laying the right shapes and sizes of flints and how to build up the wall, while taking into account existing layers.
The tricky bit is making it look neat, matching it up with existing layers of flint on either side, when filling a whole and the restriction of only being able to build up a couple of layers at a time.
While waiting for the layers to set, we got a chance to fill-in where flints had fallen out of the wall and just needed setting back in and replacing patches of missing mortar.
The wall was originally laid by Napoleonic prisoners of war over 200 years ago and is falling into disrepair where it's been blown over, knocked over or just crumbling away.
It's been patched up and repaired over the years by different groups of workers, not just in more recent times but any time since it was built. Different mixes have been used and some more successfully than others.
Day two was continuing with much the same - although we could now work on another two layers.
There was meant to be a Day three but it was cancelled due to the weather, so we missed out on the final part - which would have involved placing the capping stones.
