“The Winding Engine House, built in 1824”

Tankardstown Winding Engine House is a boiler housein the foreground, the partial remains of the engine house proper, and on its far side, the pit for winidng drums. 

In the centre of the Copper Coast Geopark near Bunmahon is an old 19th century mining complex. Here, as in other parts of the British Empire, copper was mined. The foundation walls of the mine above the main shaft, the engine house, a chimney and fragments of a building in which the steam engine was located can still be seen. The mining area is freely accessible. It is also worth taking a look at the imposing coastal section with steep cliffs and free-standing rocks on the other side of the road.

Tankardstown is one of the main complexes on the Copper Coast of mineralised rock that has been mined in the 19th century for copper ores. The site includes the industrial heritage buildings as well as the mineral veins and old mine workings.

Decommissioned in 1877 it's in ruins now. Roof now gone (original profile not discernible). Random rubble stone walls (mostly collapsed) with lime mortar. Outline of square-headed window openings with no fittings.

The great diversity of minerals recorded here are hosted in Ordovician volcanic rocks, but the minerals are a mixture of different ages. The primary ores, probably of Devonian age, occur in veins, which cut across and through the volcanics. There may be some minerals associated with the volcanic eruptions themselves too. However, the most spectacular minerals in Tankardstown mine are secondary minerals derived from oxidation or weathering of the primary ores, and are therefore quite recent, developing since mining ceased.

Main Geological or Geomorphological Interest Tankardstown is of particular interest for the diversity of minerals it has, some of which are rare. There are at least 36 different minerals recorded from Waterford Copper Coast mines, such as arsenopyrite, azurite, barite, bornite, botallackite, brochantite, chalcopyrite, chrysocolla, cobalt arsenides, connellite, copper, cuprite, dolomite, epidote, erythrite, galena, langite, malachite, pyrite, siderite, sphalerite, tennantite and tetrahedrite, many of which are found at Tankardstown. The finest examples at Tankardstown are of brochantite and the flowstones of langite/brochantite. The minerals are contained in primary veins, secondary weathered zones called gossans and as spectacular flowstone type deposits in the abandoned mine workings.

Of considerable value to the Copper Coast Geopark is the iconic remains of an engine house on the northern side of the road. These have been conserved and interpreted with the aid of the Mining Heritage Trust of Ireland and are safe for visitors to explore and enjoy.

The site is of national importance for its mineralogy. The site is part of the complex of sites along the Copper Coast, which collectively are of national importance and which are already part of a proposed NHA (Ballyvoyle Head to Tramore No 1693).

The disused mine workings are not suitable for general promotion as they presently exist. A major investment costing perhaps millions of euros would be required to make them publicly accessible as a showmine, meeting all safety requirements and regulations. It could be done with adequate funding though, and they are sufficiently interesting to be a tourism attraction that could potentially be quite successful. At present the Tankardstown Mine workings are inaccessible without specialist equipment. Collapsed shafts have blocked access to inner sections for mine heritage specialists. A fenced off open shaft from the clifftop intersects the horizontal adits underground in the mine. Underground mine workings such as these are the responsibility of the Minister for Communications, Energy and Natural Resources and permission must be sought for entry or any intervention.
