Rath of the Early Christian Period.
SMR NO: ARM 013:011
Grid Ref: H94884551
Sitename: DRUMMAN FORT
Condition: some remains
On the summit of a low rounded hill, the site is poorly preserved, but its roughly circular outline is defined by a hedge boundary and lane on the SE, and by a shallow scarp which falls up to 1.2m to the base of a shallow surrounding ditch. The platform measures 45m across N-S and the ditch appears to be c.5.5m wide and no more than 0.2m deep. The site has been heavily ploughed and the NE quadrant is almost completely destroyed.
