• OF003-032 Structure - peatland
  Description

  A single roundwood and two fragmentary pieces of brushwood on the field surface (L 3.25m min.; Wth 0.65m; D 0.075m). A bulldozer machine has extensively damaged this site. The brushwood (diam. 0.015-0.03m) survives as fragments and bark. A very fragile, possible stone toolmark survives at one end of the roundwood. The site lies in well-humified fen peat with Phragmites and woody roots. Recorded by the Irish Archaeological Wetland Unit (University College, Dublin) in 2002. The evidence is not sufficient to warrant its acceptance as the remains of an archaeological monument. The original survey description was compiled by the Irish Archaeological Wetland Unit (University College, Dublin). Assessed and revised by: Caimin O'Brien, Paul Walsh Date of upload: 23 May 2011

• OF003-033 Road - class 1 togher
  Description

  The site (L 68.5m; Wth 2.95m; D 0.26m) is orientated N-S and is constructed of morticed planks, roundwoods and brushwood. It varies in surviving width (Wth 2.7-3.25m) and depth (D 0.08-0.26m) along its length. At the N extent, it is constructed of two layers with a basal layer of predominantly longitudinal brushwood with some transverses and fragments of split timbers. Above this is a morticed plank, secured by a peg. The upper surface is formed of longitudinal planks (Wth 0.06-0.22m; D 0.01-0.048m), roundwoods (diam. 0.065-0.09m) and brushwood. The larger elements are concentrated on the W side of the site and a deposit of lighter brushwood elements is present at the E extent. Three pegs (diam. 0.055m) are set at 75-90° angles securing the larger elements in place. Woodworking is evidenced by the seven, very thin, radially split planks, by stone toolmarks on the end of one of the pegs and by the D-shaped mortice. This portion of the site is in moderately humified fen peat with Sphagnum and a very high proportion of unidentified reeds. Beyond this, to the S, there is no discernable structure evident, although there is brushwood on the field surface, along the line of the site. The S extent consists of a transverse plank, brushwood, roundwoods and some possible pegs. A chert scraper (02E0942:2) was recovered from the field surface 1.4m to the N of this sighting. This site was dendrochronologically dated to 3643±9 BC or later (Q10345). Compiled by: Irish Archaeological Wetland Unit (University College Dublin). Date of upload: 23 May 2011
