Road — class 1 togher in Derrybrennan,ticknevin

One of three toghers (see also KD012-003001- and KD012-004001-) converging on Derrybrennan townland, a small 'island' of high ground in the expanse of bog to the N of Lullymore, which were investigated by Rynne (1964-5, 35-7) on behalf of the NMI after their discovery was reported by Bord na Móna. The togher ran between higher ground in Ticknevin townland to the N and Derrybrennan townland to the S (est. L c. 1500m). Rynne traced its S limits, followed its course N for about half its length, archaeologically excavated a portion of the monument (L 9m; Wth 1m), and made some 'minor cuttings at one or two points'. The togher was found at a depth of c. 1.2-1.5m below the estimated original level of the bog's surface, which had been almost cut away. It was orientated on an approximately NNW-SSE axis and consisted of two continuous lines of parallel pairs of oak planks (av. L. c. 4.5m; Wth c. 0.4m) which were laid longitudinally on the peat and were supported at each end on transverse, oak roundwood sleepers. The planks had rectangular mortices at each end through which long (av. L. c. 0.6m), axe-sharpened, oak pegs were driven to anchor them in place. In other places, one wide plank was used instead of two narrower ones. It was subsequently radiocarbon-dated to 1200+/-20 BP (GrN-14728) (Brindley and Lanting 1998, 47).
