Located on a side road adjacent to the river Blackwater outside Lismore, County Waterford is this pair of ice houses dating from the end of the 18th century. They were built not to serve the nearby castle but by a local family, the Foleys who operated a fishery business in the area and wanted to preserve their catches. On a piece of flat land, channels were dug through which water from the river would enter and then be held by sluice gates while it froze during the winter: the resultant ice was then moved into these two round buildings which seemingly continued to serve this purpose well into the last century. The original entrance porch was to the rear, through which further doors gave admittance to each house, each measuring 6.65 metres in diameter and 4.5 metres to the top of the dome: the arched entrance in the southern chamber (next to the road) was only created a few years ago by the local authority. The cracks in the northern chamber must be a cause of concern.
