Knebworth House has been the home of the Lytton family since 1490, when Thomas Bourchier sold the reversion of the manor to Sir Robert Lytton, Originally a genuine red-brick Late Gothic manor house, built round a central court as an open square, in 1813-16 the house was reduced to its west wing, which was remodelled in a Tudor Gothic style and then was transformed in 1843-45 into the present Tudor Gothic structure.

 

The family is warned of an impending death by the sound and occasional sighting of a girl named Jenny, spinning. Other phenomena include a presence in the rooms once frequented by Edward Bulwer-Lytton who died in 1873, and some believe he may have decided to remain there.

 

A guest sleeping in the Queen Elizabeth Room reported being awoken by a mystery girl with long, blonde hair leaning over the bed. Another unknown female has been sighted in the Picture Gallery
