Brocket Hall

"Night of the Demon - 120 miles from Stonehenge is Brocket Hall, home to Dr Julian Karswell, the hoity-toity man with supernatural powers. The stately mansion is where Karswell casts a spell and conjures up a whirlwind to convince the skeptical Holden. In the film the house is supposed to be in Warwickshire, but in reality it’s in Lemsford, near Welwyn Garden City, Hertfordshire. You first glimpse it from Paine Bridge, over the River Lea. Its riverbank looked a little bushier back then. The only real difference now is the sharper landscape design. To visit the hall today you will need a fat wad of cash. Its website boasts “exceptional golf” and “afternoon tea”. You can rent it for corporate events, weddings and general posh private parties."
