As befits the oldest inhabited castle in Ireland, Malahide Castle has many ghostly traditions. Many historic castles and houses have one ghost, some have two or three, but Malahide Castle has five.

Fist there is the spectre of young Lord Galtrim,the second spectre is that of the Lady Maud Plunkett,the third ghost is that of the Chief Justice and the fourth ghost is a jester by the name of Puck.

The fifth ghost is more interesting, historically speaking and is that of Miles Corbett, the Roundhead to whom Cromwell gave the Castle and property during his protectorate. At the Restoration Miles was deprived of his property and made to pay the penalty of the many crimes he had committed during his occupancy, and which included the desecration of the chapel of the old abbey near the Castle. He was hanged, drawn and quartered and when his ghost first appears it seems to be a perfectly whole soldier in armour, but then falls into four pieces before the eyes of anyone who has the unpleasant experience of meeting it.
