History
The castle is situated in Ireland's most ancient primordial oak woods, once the hunting grounds of Ireland's druids. In the sixth century it was part of the ancient monastic site of Lynally, which itself was in the ancient Durrow monastic settlement.

Chareville Castle grew from paper doodles in early 1798 to grandiose plans by the end of that very eventful year in Ireland. It owes its 'Tin Soldier Fortress' look to the celebration of victory over the third French revolutionary expedition to Ireland, the first decisive victory by Britain over the revolutionary republican movement. It took 14 long years to complete this great gothic dream, a monument not only to a now forgotten power, but also to the people who made it possible, the Irish craftsmen and impoverished people.

It is today Ireland's most important example of gothic revival architecture, the leader of the Francis Johnston School of Architecture, his masterpiece. Its restoration is now on-going.

Phenomena
The Charleville Castle has been searched over for years by parapsychologists and forensic investigators with equipment in search for poltergeists. The story goes that the castle was built over the top of an ancient druid burial ground where people were once buried alive in an attempt to stop the spread of the black plague centuries before.

There have also been suggestions that the man who built it practised devil worship. Spooky happenings have been taking place as recently as at the turn of the century, when a young girl fell to her death from a staircase banister whose spirit still roams around the castle.

Investigation
Early on in the investigation, the team were spooked by doors opening and closing under their own power. In the dungeons, Derek picks up the residual energy of an evil jailer, who strikes him on the arm. Several team members feel a tickling sensation of their heads and a candle flickers without any breeze present.
