A bit of wall architecture
I checked the Mono Monday theme while walking the block- architectural glimpses. If you look carefully you will glimpse stones of different shapes and going in different directions , all carefully placed to build the wall with no mortar - that's why its dry ! . Damn clever these wallers. But do not try and climb over one , you will likely dislodge some stones and its jolly difficult to put them back in the right place.
