This is the lower of two peaks in the Mourne Mountains called Slievenaglogh, the other being situated further north near Hare's Gap. This Slievenaglogh overlooks the Silent Valley Reservoir, constructed in the 1920s to supply water for Belfast. Before it was flooded, the Silent Valley was known as the 'Happy Valley'. Labourers from the Happy Valley constructed the Mourne Wall for the Belfast and District Water Commissioners to delimit the catchment area. It is 2-2.5m high and 1m thick, encloses 9,000 acres of land (3,600 hectares) and passes over the summit of many of Mourne's highest peaks.
Slievenaglogh is the 751st highest place in Ireland. Linkback: https://mountainviews.ie/summit/635/
