Castleshane is a small village on the outskirts of Monaghan town in the north of County Monaghan in Ireland. Castleshane, or Caisléan an tSiáin in Irish, translates as the castle (or fort) of the fairies and not 'the castle of Shane' as most believe. The village is situated on the N2, the main road from Dublin to Derry and Letterkenny, and is located approximately 6 kilometres from Monaghan town and 17 kilometres from Castleblayney.
