What is recorded here

Dunmahon Castle rises four storeys above County Louth, its rough limestone and greywacke walls still bearing the murder hole and bar cut for a door that closed against invasion. Henry Townley lived inside that defensive geometry in 1659, climbing the northeast spiral stair and stepping onto a wall-walk built to shed rain and resist attack. The missing wooden steps and cramped upper chamber suggest a house shaped as much by fear as pride, where every angle served to keep another person out.
