Mound in Derroon

A small rectangular earthwork is located just outside the outer bank of Derroon rath (SL033-046001-) at NNE. This earthwork consists of a raised rectangular area (4m N-S; 4.7m E-W) defined by an earth and stone bank (int. H 0.3m; ext. H 0.45m). The interior is slightly concave in profile and clear of overgrowth. On the SE side of this earthwork, outside the base of the bank at the SE corner, a shallow drain (D 0.3m) with an earthen bank (H 0.45m) on its N side (both orientated E-W) has been dug extending E to a field boundary. Roughly 1.5m to the W of the rectangular earthwork is a series of low earth and stone mounds (diam. 1.5-2.5m; H 0.8-1m). A low earthen bank (ext. H 0.25m) which runs parallel to the W edge of the rectangular earthwork defines the limit of these mounds on the E side. Compiled by: Archaeological Survey Unit, UCC with revisions by Patrick F.
