Recorded monuments

• DG107-089 Megalithic tomb - unclassified
  Description

  This monument stands toward the SE end of a broad ridge in rolling pasture. It is 1km S of the River Erne and commands an extensive outlook across the river basin. There is a more restricted outlook to the S and E. The surviving structure consists of two orthostats lying E-W. These seem to represent the side of a gallery at least 6.2m long. The orthostats stand in a substantially levelled, low, subrectangular mound that survives to the E of a field fence crossing the W end of the structure. It measures 12m E-W and narrows from 17m wide at the W to 13m at the E. A drop in ground level of 0.3m defines the edge of the mound. Apart from a small piece of outcropping rock to the E of the eastern orthostat, the mound is entirely grass grown. The eastern orthostat is 1.3m high. The western, slightly N of the line of the eastern one, is 0.95m high. A loose slab, 0.3m N of this, lies at the edge of the field fence crossing the site and measures 1.45m by 0.95m by 0.25m thick. Three stones, one to the N and two to the S of the western orthostat, shown in Holly's (1975-6) plan of the monument are quite loose and do not form part of the structure. According to mid-19th-century OS documents, the surviving orthostats represent the S side of the monument, the opposite side of which had been removed before then (Fagan 1845-8; OS Revision Name Book, 1847-50). These stones clearly formed part of a substantial E-W-aligned megalithic gallery, but it is not possible to classify it.
