The site only came to light because a road had to go through it.

In 2006, excavations carried out ahead of the N9/N10 Kilcullen to Waterford road scheme uncovered two iron smelting furnaces, two charcoal kilns, and what appears to have been a smithing hearth. Iron smelting at this scale requires sustained, intense heat, which is why charcoal kilns, used to produce the high-temperature fuel needed for the smelting process, were built so close to the furnaces themselves. Radiocarbon dating of samples from three of these features returned dates ranging from 729 cal BC to 51 cal BC, placing activity at the site across a broad sweep of the Iron Age. Post-holes, charcoal spreads, and other features found in the same area returned even earlier dates, suggesting the ground had been in use for some time before the metalworking began. The excavation was conducted under licence number E2500 and published by Wren in 2009 and 2010.
