Man-made underground passage in Annagh

This filled-in Man-made underground passage is now inaccessible. The rock-cut entrance measures 1.3m E-W × 1m N-S and is 1.75m deep at present. It is situated on a slight ridge in a grazing field which slopes to the SE. The above description was derived from the 'Archaeological Survey of County Donegal. A description of the field antiquities of the County from the Mesolithic Period to the 17th century.'
