Prince Charles has visited Jewish and Muslim students at a college which is promoting inter-faith dialogue.
The prince took part in an inter-faith discussion
He was at the Leo Baeck College in Finchley, to join a discussion between its rabbinical students and those from the Muslim college in Ealing.
The prince, who is interested in tolerance between faiths, was visiting on the 50th anniversary of the college.
Pupils from Akiva Primary school also sang songs in Hebrew and Arabic.
Among those taking part in the discussion was Rukhsana Shah, who told the Prince of Wales: "We have been observing each other's prayers and it's the first time I have witnessed a Jewish prayer."
He also planted a flowering cherry tree in the grounds of the college in memory of his grandmother, the Queen Mother.
The prince also visited the Jewish Museum, which is also based in the Sternberg Centre, where he met 95-year-old Leon Greenman, who lost his wife and son at Birkenau,
There is an exhibition at the museum dedicated to Mr Greenman's experiences.
He was kept at six camps during World War II, including Auschwitz and Birkenau, where his wife Else and son Barney died in the gas chambers.
Among items in the exhibition are Else's dress, and one of Barney's outfits.
"All I've got are photographs and memories," said Mr Greenman.
"The baby didn't live three years when his mother and him were gassed by the Nazis."
He has dedicated his life to telling people about the Holocaust and spends every Sunday at the museum, telling children about his experiences.
Prince Charles told him: "I'm so glad to have the chance of meeting you."
