The kerbstones are of a kind of rock called greywacke and they are thought to have been quarried and then dragged or carried by boat to the Boyne Valley from Clogher Head some twenty kilometers to the northeast, up the coast from the mouth of the Boyne.It is made up of grains, usually of quartz or feldspar. If the grains are very small then the sedimentary rock may be called a siltstone. These fine grained sediments often flake fairly easily and if used as kerbstones quite often look rather worn and battered.
