Keady Quarries, Keady Road, Largyreagh, Keady Mountain, Limavady, Co Londonderry

Dramatic mass concrete structures situated just below the crest of Keady Mountain which give the hill a silhouette comparable to the natural cliff of Binevinagh in the distance to the north west. The main structure is a rough concrete cube which sits out of the hill like a Sphinx with three sloping fins pawlike in front. There are two small openings to one side on the front (west) elevation. This was constructed in five pours (15m) from the top of the three pours high fins (9m). Rusted steelwork connects the top of the fins. There are no openings to the sides. To the south are three concrete walls stepping down from the apex, once supports for chute now removed. To the north, the second major structure, a rectangular trough three pours high set into the hillside so that only the west face is exposed. Directly below are four fins two pours high supporting the blank box above. Further to the north are the remains of single storey office buildings with concrete block walls and rusting tin roofs. A wide flat area sits directly in front of the buildings and is covered in fine hard-core before natural slope of the hill is resumed. Above the objects is the main quarry worked 500 metres approximately back into the hill. On the crest of the hill above the quarry are the remains of an old burial ground and a stone circle.
