The final night finds the Most Haunted team investigating the Royal Apartments of Moncalieri Castle - built by the Knights Templar - legendary keepers of the Holy Grail.

It has long been held that the Knights buried the Grail somewhere within Turin and perhaps it is no coincidence that The Shroud also found its way to the city - perhaps just two of many sacred elements that protect the city from the terrible influence of the Devil - will the team be able to prove psychically once and for all that goodness will prevail?

The tales of spirits here never end. Bella Rosan, a former bride of the Prince of Savoy, is a restless soul trapped here, she was involved in dark magic and black masses - and appears to be searching for something at the castle - but nobody knows what she is looking for. Can we get to the bottom of the mystery?

One of the King's daughters is said to have been murdered here, her spirit is often seen crying out and she shakes the sleeping awake, begging for help! The ghost of the King is said to be seen fleeing through the building trying to escape from who knows what terrible evil.
