When most people think of castles, the chances are they think of Disney princesses, knights in shining armour and, of course, our very own royal family.
But, beyond all the grandeur, there's one thing very commonly associated with castles - and that's whether or not it's haunted.
It has long been said that the Queen 's current residence, Windsor Castle, is the most haunted of all the royal residences, with more than 25 paranormal experiences involving ghosts and spirits having been reported.
However, according to MyLondon, there's one royal residence, which the Queen has never lived in, which is said to be haunted by the ghost of her scandalous relative - and it's not even a castle.
York Cottage is a relatively humble home - for royal standards - situated on the grounds of Sandringham Estate, which was originally built as an overflow for the main Sandringham house.
In 1893, the house, which is sometimes referred to as the 'Bachelor's Cottage' was given as a wedding gift by King Edward VII (then Prince of Wales) to his son and new daughter-in-law, the Duke and Duchess of York, who would later become King George V and Queen Mary.
Prior to this, York Cottage had been lived in by Prince Albert Victor, the eldest son of King Edward VII, until his death in 1892 from influenza.
King George V and Queen Mary loved living in the cottage, where five of their six children were born, as they preferred to live a simpler life, with the king once describing the home as resembling 'three merrie England pubs joined together.'
These days, York Cottage is used as the estate office for Sandringham while also providing accommodation for employees. But, while no current royals live in the property, it has been claimed that one royal 'stayed behind.'
Prince Albert Victor, Duke of Clarence and Avondale was born on January 8, 1864 at Frogmore Cottage in Windsor but spent many years living at York Cottage.
The great-uncle to the Queen was a controversial figure, having once been a key suspect in the Jack the Ripper murders and also thought to be involved in the Cleveland Street Scandal of 1889.
There were two completely unfounded theories behind claims he was the Whitechapel killer, with one suggesting Albert had contracted syphilis from a prostitute in the West Indies which made him go on a murderous, vengeful rampage as the disease spread to his brain, turning him mad.
The second theory suggests the prince fell in love, had a child with and secretly married a Catholic girl in Whitechapel, but due to the undesirable match, the royal family hired agents to kill anyone with knowledge of the secret marriage and child.
However, the prince - who was known as Eddy - to family and friends, was actually 500 miles away with his grandmother, Queen Victoria, in Balmoral, Scotland, on the night of the double murder, proving he could not be the killer.
In 1891, Albert proposed to Princess Victoria Mary of Teck, who would later become Queen Mary, and they planned their wedding for February 27, 1892. However, between 1889 and 1892 an influenza pandemic struck the country and the prince fell ill, eventually developing pneumonia.
Less than a week after his 28th birthday, Prince Albert Victor died at Sandringham House in Norfolk, surrounded by his family and fiancée.
If ghostly tales are to be believed, it is said that the prince's ghost can still be seen at York Cottage.
