What is recorded here

No visible entrance. Derrendub Fort is a shallow earthen ring in West Cork pasture, wide enough for oak trees to grow inside its bank and a large slab to sit at its centre. The story told about it is that it belongs to the fairies, but the shape suggests human hands: a rounded border, a drainage cut outside, and stone facing where the west rain would strike. Perhaps it was a farmstead, a refuge or a boundary marker before becoming the kind of place people stop asking questions about.

In pasture, on break in NNW-facing slope. Circular raised area (32m N-S; 34m E-W) enclosed by earthen bank (H 1.7m); external fosse consists of drainage channel NNE->SW in which stream flows. Bank stone-faced externally to W. Enclosure planted with oak trees; large slab in centre. The above description is derived from the published 'Archaeological Inventory of County Cork. Volume 1: West Cork' (Dublin: Stationery Office, 1992). In certain instances the entries have been revised and updated in the light of recent research. Date of upload/revision: 14 January 2009

Derrendub Fort, Glanatnaw is a circular early-medieval ringfort, likely dating to between the 5th and 10th centuries, characterized by a raised central area and a substantial earthen bank with a stone-facing. Local tradition, common to many such sites, may associate it with fairy lore or ancient Irish settlers, though specific folklore is not recorded.
