Standing stone in Aghadreenan

A standing stone .8m high × 0.5m wide; NW-SE. The date 1819 is incised on it. It is said locally that it was erected in the 17th century by the Dill family. It is also said to be an ogham stone but there is nothing visible to support this claim. Situated in a prominent position close to the crest of Crockastoller hill. 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.' Compiled by: Brian Lacey with Eamon Cody, Claire Cotter, Judy Cuppage, Noel Dunne, Vincent Hurley, Celie O'Rahilly, Paul Walsh and Seán Ó Nualláin (Lifford: Donegal County Council, 1983).

Likely prehistoric in origin, the stone's alignment and form suggest a ceremonial or territorial function, though its 1819 inscription and local tradition linking it to the Dill family in the 17th century complicate its dating. No ogham or other prehistoric inscriptions are visible, and its original meaning or use remains unclear.
