With its sandstone columns and Union Jack fluttering in the wind, Saint Hill Manor looks like a quintessential English country house. Set in rolling Sussex countryside on the outskirts of East Grinstead, it has been the seat of numerous moneyed families over the centuries.
Yet visitors approaching the gates are confronted by a bank of security cameras and a troop of guards.
Saint Hill Manor is the spiritual home of Scientology in the UK, where church founder L. Ron Hubbard spent almost a decade refining his beliefs.
And the divorce between Tom Cruise - one of Scientology's most famous and zealous adherents - and Katie Holmes has put a new spotlight on the workings of the new-age faith.
The US media has been quick to question whether Cruise's attachment to Scientology - whose adherents eventually "discover" through paid-for courses that we are all extra-terrestrial entities known as thetans trapped in human bodies by an evil Lord Xenu - was a factor in Holmes's decision to separate.
