Behind the turrets of one Scottish mansion lies a bridge with a reputation nobody can quite explain.
A Scottish chemical-works family built a hilltop mansion, but their estate was split in half by something wet and noisy. What did they build a bridge over?
A waterfall John White, son of the original owner, built a new road and the Overtoun Bridge so the east and west sides of the estate could finally meet.
A London doctor inherited a grand Scottish mansion but hardly ever visited Scotland. What did he decide to do with it?
Gave it to the town Dr Douglas White handed Overtoun House to the people of nearby Dumbarton, and it later served as a home for wounded soldiers and then a maternity hospital.
The respected architect who designed this mansion was later overshadowed by a family member who became infamous in a murder case. Who was it?
His daughter Glasgow architect James Smith was the father of murder suspect Madeleine Smith, and he died before the house was even finished.
Starting in the 2000s, news reports described a strange kind of visitor appearing to leap off this mansion's bridge on purpose. What animals?
Dogs Some blamed supernatural forces, while others said the dogs chased tempting scents and lost their balance on the bridge's sloping wall.
After falling into abandonment, this old mansion found a new career pretending to be other houses. Where might you have seen it?
In the movies Overtoun House played two different homes in Cloud Atlas and also appeared in the film Regeneration and a music video, while a Texas pastor now runs it as a Christian centre and tearoom.
