The Tower of London is actually 21 towers, each with its own story, but none so gruesome as the famous Bloody Tower. It is one of the most haunted collection of buildings in Britain.

The tower once served as a prison and a place to be executed. Most of the ghosts are said to be victims who were beheaded or murdered. Many of the ghosts - men, women, children, even a troop of soldiers - are seen walking around, standing at different tower windows or walking through walls.

A legend attached to the tower claims that if the Ravens were to ever leave The Tower of London that the Monarchy would collapse along with the empire. King Charles II wanted all the ravens destroyed for some reason, but decided not to when he was told the legend.

We now think we know why the location is marked on Ludlow's map.

Other Tower hauntings:

The Tower is a veritable hotbed of otherworldly action. The list of ghosts attached to the place reads like a who's who of English History.

The earliest known sighting of a ghost at the Tower was that of St Thomas a Becket in the 13th century.

Other ghosts that have been seen are two small boys walking hand in hand throughout the Bloody Tower. When King Edward V died, his brother Richard took Edward's two sons away from their mother. The Crown Princes, 9 and 12, were taken to the tower for their protection. They were never seen again. In 1674, two small skeletons were discovered in a chest beneath the stairway of the White Tower. It is assumed that they belong to the two Crown Princes.

Sir Walter Raleigh and a Duke of Northumberland both have walks within the grounds named after them, due to their seeming love of plodding up and down them, long after they've shuffled off this mortal coil. Guy Fawkes's agonising screams are still said to drift up from the area where he was tortured, chilling the blood of all who hear it.

One poor ghost is even being chased by another - The bungled execution of Lady Salisbury is said to be enacted on Tower Green, on the anniversary of her execution in 1541. She ran from the block in hysterics with the axe man chasing behind her. She was finally felled with a number of heavy blows from behind, the whole bloody scene is said to be replayed in full.

The guards and sentries of this place haven't had an easy ride of it down through the centuries either. One guard paid the ultimate price after stabbing at what he believed to be a bear. When the blade passed straight through the creature, the man became quite unhinged. He related the few scant details to E. L. Swifte, (who had experienced and recorded the ghostly tale of the cylinder). The poor man promptly died three days later from shock. The sighting has been dated to January in the year 1815 or 1816.

Another recorded incident was on the 12th of February 1957 when a guardsman at the Salt Tower (at 3 o'clock in the morning) heard something on the sentry-box roof. He investigated and saw a shapeless white 'ghost' on the top of the tower - Some say that it could have been Lady Jane Grey (the 9-day queen), who was beheaded on Tower Green (which is a few hundred yards) away in 1554.

He yelled for the guard captain and the duty warder, who searched the tower, but found nothing. Lady Jane Grey is said to appear every year on the anniversary of her death - the 12th February.

December 1995, an American tourist was taking photos of her vacation to England and the Tower of London. She took a picture of Traitor's Gate. After returning home the film was developed and in the shot you can clearly see a hand in the foreground, wearing a 16th century Yeoman Warder Uniform.
