Ballycorus Leadmines

Open-cast mining began at Ballycorus around 1807 on the western side of Carrickgollogan hill, close to the later site of the flue chimney. The site was taken over by the Mining Company of Ireland (MCI) in 1826 who undertook underground mining in the area up until 1863. The ore from Luganure was carried by horse and cart to the railway station at Rathdrum where it was transferred to a train and brought to Shankill. A siding on the Harcourt Street railway line was built near Shankill station to receive the trains. surrounded by some of the surviving buildings from the leadworks The lead ore was processed using a reverberatory furnace, the bed of which was dished so that the molten lead would trickle down the sides to the centre from which it was run off into moulds. Lead shot was also manufactured: the first shot tower was built in 1829 and was described by Weston St. John Joyce in The Neighbourhood of Dublin (1912) as “a handsome and substantial structure, having a spiral stairs within, terminating in an artistic iron veranda on the outside”. A second shot tower was built in 1857. A process had been discovered in the 1770s whereby additional quantities of lead could be extracted from the fumes emitted by reverberatory furnaces if the vapours could be trapped long enough to precipitate the lead. The precipitated lead deposits were scraped out of the flue by hand and many of the workers subsequently died of lead poisoning, giving the surrounding area the nickname “Death Valley”. The distinctive granite flue chimney with its external spiral staircase and viewing platform quickly became a noted landmark and was marked on Admiralty charts as a point of reference for mariners. Photographic records show that the flue chimney was originally much taller with an extra brick section, now dismantled, rising above the viewing platform. It is the only example of such a flue and chimney to have been built in Ireland. Weston St. John Joyce noted that the flue was “stated to be one of the best constructed in the United Kingdom”. ==Present day==

The most prominent surviving remnant of the leadworks is that of the flue chimney. The land around the chimney is owned by the State forestry company Coillte and managed by the Dublin Mountains Partnership. A waymarked walking trail around the forest, called “The Lead Mines Way”, leads to the ruin of the chimney. The top third of the chimney has been removed as it was deemed unsafe as has the lower section of the external stairs. Much of the flue, along with many of its inspection hatches still exists and can be explored. In addition, a number of buildings from the smelting works situated in the valley below also survive to the present day. These industrial buildings, all built from granite, include furnaces, purification tanks, lime kilns, stores, workers' cottages and the manager's house. The 1857 shot tower is also extant. The report graded the site as Class IV: a site “requiring specific monitoring on particular waste piles, discharges or stream sediments on a five-yearly basis”. ==References==
