To mark today's 80th anniversary of the liberation of Auschwitz, an historic house next door to the death camp - featured in the film The Zone of Interest - is being opened to the public.

House 88 was the family home of Rudolf Höss, the camp commandant, who lived there with his wife and children for four years of the war.

With support from Unesco, the Polish foreign ministry and a former US ambassador to the UN, Mark Wallace, it's being turned into the Auschwitz Research Centre on Hate, Extremism and Radicalisation.

Not everyone approves. Simon Schama, the historian, worries that it won't teach anyone about what Jews suffered in the camp.

Wallace tells the Observer it will do that and more - reminding visitors hatred can lurk "in the ordinary house next door".

King Charles, Emmanuel Macron, German President Frank Walter Steinmeier and other leaders join about 50 survivors for a remembrance ceremony today at the camp where 1.1 million people were murdered.
