Somewhere beneath the worked-out bogs north of Lullymore in County Kildare, a road has been slowly dissolving for over a thousand years. It was never a road in the modern sense, but a togher, a trackway of timber laid across soft or waterlogged ground to allow passage where the peat would otherwise swallow a traveller whole. This particular example stretched an estimated 1,500 metres across the bog, connecting two patches of higher ground that rose like islands from the surrounding wetland: Derrybrennan townland to the north, and Lullymore West to the south.

The togher came to light after Bord na Móna, the state peat company whose machines harvested the Kildare bogs on an industrial scale through much of the twentieth century, reported its discovery. A researcher named Rynne investigated on behalf of the National Museum of Ireland, examining both ends of the structure, though the published account from 1964 to 1965 was light on detail. What local reports did describe were transversely laid planks, each around 2.4 metres long, exposed in the softer peat where turf-cutting machines had sliced through the road. Radiocarbon dating later placed the togher's construction somewhere between AD 775 and 892, placing it firmly in the early medieval period, a time when the monastic landscape of Ireland was at its most active. This matters because the southern end of the togher, at Lullymore West, appears to align with a laneway that leads towards an early monastic site. The road was not merely practical; it was part of a network connecting people to a place of religious significance. Two other toghers converge on the same Derrybrennan island, suggesting this small rise of dry ground was a meaningful node in the early medieval geography of the bog.
