Senior politicians, dignitaries and religious leaders joined some of the few remaining survivors in central London for a service on Holocaust Memorial Day.
UK Chancellor George Osborne told MPs that the new memorial and education centre are among recommendations from the cross-party Holocaust Commission.
It was set up by British Prime Minister David Cameron to consider how awareness and remembrance of the Holocaust can be maintained as the final witnesses pass away.
"I think across the House we can come together to commemorate this day but also to make sure it is never forgotten what happened in the Holocaust and we never repeat its mistakes," he said.
"As this is the 70th anniversary of the liberation of Auschwitz, we should remember the inhumanity that happened there and the suffering of those who died and who live with the memories of the Holocaust, and vow as a nation to keep its memories alive."
In central London, around 1,000 guests marked one of the most defining events of the 20th century and one of the candles will be lit at Auschwitz itself, where European leaders are expected to join survivors to honour the millions murdered during the Holocaust.
