A headmistress thanked Hitler for his warm-hearted hospitality in remarkable documents that detail a British schoolgirls Berlin exchange visit in 1937.
The newly discovered archive outlines how 16 pupils at the Simon Langton School for Girls in Canterbury, Kent, came to spend their 1937 Easter holidays in Berlin on a foreign exchange trip.
The school went to extraordinary lengths to try and arrange a face-to-face meeting between the girls and Adolf Hitler.
The pupils, aged about 15, were to present him with gifts including a photo of Canterbury Cathedral and a presentation copy of The Canterbury Tales.
However, while they did not end up meeting Hitler, they were shown around the Reich Chancellery by his minister Otto Meissner.
