Beneath the streets of Romania's capital, a living hell

When Ceausescu fell there were tens of thousands of children in orphanages and in state "care" in Romania. But in 1990 a series of reports revealed what a nightmarish misnomer that was. Scenes of neglect and cruelty reminiscent of the concentration camps.

The entrance to this underworld is a hole in the pavement on a traffic island in front of the station. By late afternoon they start to wake up, clambering up out of the ground like the undead.
