With sloping red-tiled roofs, trimmed lawns and a shop selling home-baked ginger biscuits, Villa Baviera looks like a quaint German-style village, nestled in the rolling hills of central Chile.

But it has a dark past.

Once known as Colonia Dignidad, it was home to a secretive religious sect founded by a manipulative and abusive leader who collaborated with the dictatorship of Augusto Pinochet.

Paul Schäfer, who established the colony in 1961, imposed a regime of harsh punishments and humiliation on the Germans living there.

They were separated from their parents and forced to work from a young age.
