Gralstead House
From Tardis Wiki, the free Doctor Who reference
Gralstead House was the home of the Scrivener family in Highgate, London. It was built in 1733 by Sir Joseph Scrivener. It had a family mausoleum.
It was home to a so-called family curse in which the skies appeared to shift, which was in fact simply the representation of looking down a portal into another part of the galaxy, focused on the house, from which Mordrega could enter into Earth. (AUDIO: The Ghosts of Gralstead).
