Place & story
Materials and routes through the parish
In 1837 Samuel Lewis recorded quarries at Greenfield in Castletown parish, supplying stone for buildings and road repairs. The parish lay beside Dundalk Bay, where roads towards Castleblayney and Armagh branched near the village. Streams from Philipstown, Dungooley and Forkhill joined within the parish to form the Castletown River before reaching the sea. Lewis reported that the tide travelled nearly a mile upstream and regarded this tidal reach as an aid to navigation. He did not specify cargoes or vessels. [2]
