Barrows
A monument that cannot be seen with the naked eye, yet still registers on satellite imagery taken on a November afternoon in 2018, sits in reclaimed pasture outside Lissard in County Limerick.
This ditch barrow, a prehistoric burial mound defined by a surrounding ditch rather than by upstanding earthworks, has been so thoroughly absorbed into the improved farmland around it that no surface remains were visible on aerial survey imagery captured between 2011 and 2013. A few years later, conditions were apparently just right for a faint outline to ghost back into view from above, a pale crop or soil mark betraying what lies beneath.
The barrow sits in the eastern quadrant of a cluster of fourteen such monuments, a concentration that speaks to sustained prehistoric use of this landscape over a long period. An enclosure of a different type lies roughly 270 metres to the south-west, and a barrow cemetery stretches away to the south and south-south-west, suggesting this corner of Limerick was once a carefully organised place of the dead rather than an unremarkable stretch of grazing land. None of this was formally recorded on Ordnance Survey Ireland historic maps. The site came to archaeological attention through a survey carried out by Seán P. Ó Ríordáin in 1936, published that same year, which documented the broader group and placed this barrow within it. Ó Ríordáin was one of the central figures in Irish field archaeology during the mid-twentieth century, and his methodical surveys of Limerick and Tipperary identified many monuments that had otherwise gone unrecorded.
There is nothing to see here in the conventional sense. The field looks like farmland because, functionally, it is farmland. The value of visiting, if one were inclined to, lies less in what is visible on the ground and more in knowing what the ground contains. The site is not marked on standard walking maps, and access across private agricultural land would require landowner permission. Those with an interest in remote sensing or aerial archaeology may find more to engage with by examining the Google Earth orthoimage taken on 18 November 2018, where the faint outline noted in the records can still be traced. The monument is recorded in the Archaeological Survey of Ireland database, compiled in this instance by Fiona Rooney and uploaded in July 2021, where the survey plan from Ó Ríordáin's 1936 work is also held.
