Dungeon!!!!Contrary to what many believe, Dungeons in castles were not in the basement! We will save the reason for that for now, and will be delighted to explain all when you arrive!
The Dungeon in Ballyhannon Castle is between the Great Room (on the third floor) and Bedroom 3 (on the fourth floor).
This picture shows the Minstrels’ gallery which overlooks the Great room, and access to the Dungeon is right beside this.
