    The Mourne Wall (Irish: Balla an Mhúrn) was constructed to enclose a catchment area of the Silent Valley Reservoir in the Mourne Mountains, Northern Ireland. The 1.5 metres (4 ft 11 in) high stone wall, which was built to keep livestock from contaminating water supplies, took almost twenty years to complete (1904 to 1922). The project was overseen by the Belfast City and District Water Commissioners.

    The wall was crafted from natural granite stone using traditional dry stone walling techniques. On average the wall is about 1.5 m (4 ft 11 in) high and 0.8 to 0.9 m (2 ft 7 in to 2 ft 11 in) thick and is estimated to be 19.5 mi (31.4 km) long Stonemasons worked from March to mid-October for 18 years to build the wall.
