J2825 : The Mourne Wall, Slieve Muck

The Mourne Wall, Slieve Muck
The Mourne Wall, Slieve Muck
The Mourne Wall on Slieve Muck is different from the rest of the wall as it is not constructed of granite but of a Silurian rock. The construction of this particular section is almost identical to that of nearby Batt's Wall J2825 : Batt's Wall, Slieve Muck, leading me to think that Batt's Wall extended over Slieve Muck to Carn Mountain and this section was simply incorporated into the Mourne Wall. From here the wall snakes down towards Slievenaglogh - see J2923 : Mourne Wall near Slieve Muck.
The Silurian rock used here is the oldest in the area and was originally formed some 400 million years ago; the famous granite also found here was formed a mere 60 million years ago.
The Mourne Wall

The Mourne Wall is a 22 mile long wall in the Mourne Mountains. It was built between 1904 and 1922 by the Belfast Water Commissioners to enclose their catchment areas in the Mournes and protect the area from the effects of cattle and sheep on the water course LinkExternal link . The wall is predominately constructed from local granite using traditional dry stone walling techniques; on average the wall is about 1.5 metres high and 0.8 to 0.9 metres thick. It is not uniform in construction along the entire length - the 'classic' granite wall is only to be found north of Carn mountain and Long Seefin with particularly impressive sections on Slieve Commedagh and Slieve Donard; elsewhere it largely resembles the traditional dry stone walls found elsewhere in the Mournes and south County Down. In places, such as Slieve Muck, the wall is not constructed of granite at all.
