Covid has reduced the amount of traffic so it gave me the chance to rebuild  this wall.

I'd already removed the tops, although they were mostly triangular I was going to have to create some other tops from suitable stone.

(Above)  This is part way through the re-build.  Notice that there are few  gaps between stones which reducesthe amount of rubble fill you need.  (Below)  Over many years the fill erodes, becomes smaller and eventually falls down the inside of the wall leaving large 'cavities' or gaps into which the building stone gradually collapses into - as you can see in the photograph below.  Which I why this wall has partially collapsed.

😀 And here's the finished job (below)
