Hardly anyone knows about the strange and haunting Dr Guislain Museum located in a quiet Ghent suburb.
It occupies one wing of a model psychiatric institution founded in 1857 by Dr Jozef Guislain.
Visitors can wander through chilling deserted wards still furnished with iron beds and old medical equipment.
One room contains a terrifying mechanical saw used in operations to remove the top of the skull.
The temporary exhibitions are always fascinating, as is the extensive collection of outsider art. Almost no one leaves this museum untouched.
