Perhaps the most haunted castle in Ireland is Leap Castle. More than 400 years ago, in 1532, brother turned against brother to shed blood. One was a warrior who rushed into the chapel and used his sword to slay the priest who was his brother. The priest fell across the altar and died. The chapel is known as Bloody Chapel since that time. The dungeon in the castle is called an oubliette. Prisoners pushed into the oubliette fell eight feet onto spikes coming up from the floor.
