Settlement Sites
Beneath what is now a GAA pitch in Deanstown, in the parish of Castleknock on the western fringe of Dublin, three shallow pits once held the scorched, fire-cracked stone that is the calling card of a fulacht fia.
These Bronze Age cooking sites, found in their thousands across Ireland, typically consist of a mound of burnt and shattered stone beside a water trough, where rocks heated in a fire would be plunged into water to bring it rapidly to the boil. They are among the most common field monuments in the country, yet individual examples rarely attract much attention, partly because they tend to survive as unremarkable humps in fields and partly because the question of what exactly they were used for, whether cooking, bathing, or some other communal activity, has never been definitively settled.
This particular site came to light through a geophysical survey and subsequent excavation carried out in advance of the construction of the GAA pitches, under licence number 13E134Ext. Archaeologists uncovered three pits, each filled with the characteristic burnt mound deposits. Pit 1 was oval, measuring 1.7 by 1.1 metres; Pit 2 was circular with a diameter of 1.8 metres; and Pit 3, the smallest at 1.1 by 0.8 metres, was associated with what appears to have been a trough measuring 2.1 by 1.7 metres. A sample of hazel recovered from the fill of that trough was radiocarbon dated to between 1917 and 1747 BC, placing the site firmly in the Early Bronze Age. The findings were documented by Coughlan in 2013, and compiled for the record by Christine Baker.
There is nothing to see at ground level today; the pitches were built and the archaeology now lies beneath them. The value of the site is less in any surviving visible feature and more in what the excavation record tells us: that ordinary Early Bronze Age activity was taking place in this part of north County Dublin more than three and a half thousand years ago, long before the suburban parishes and playing fields that now define the landscape. The archival record, rather than the ground itself, is where this site now lives.
