The children saved by Sir Nicholas Winton from Nazi death camps have unveiled a monument in Prague’s main train station to honour their parents.

Sir Nicholas arranged eight trains to carry 669 children, most of them Jewish, from Czechoslovakia through Germany to Britain at the outbreak of the Second World War in 1939.

He died in 2015 at the age of 106.

The children were sent to foster parents. At home, most of their parents died in the Holocaust.

The Farewell Memorial is a replica of a 1939 train door, with the hands of children on one side and those of parents on the other.

Milena Grenfell-Baines, one of those saved, said on Saturday the monument was a belated expression of thanks.
