The Prince of Wales is to unveil a permanent memorial in central London to the 202 victims of the Bali bombings.
The sculpture will be covered in individually carved doves
The ceremony will take place on 12 October - four years after the attacks on the Indonesian island.
Survivors of the attacks, friends and relatives of the 28 Britons killed and dignitaries from other nations affected are due to attend the event.
The sculpture at Clive Steps, opposite St James's Park, will comprise a marble globe with 202 carved doves.
The UK Bali Bombing Victims' Group said it was grateful to the Foreign Office, the Department for Culture, the Royal Parks and others for helping to secure the memorial.
"This is a significant moment for all those affected by the bombings and in particular those who lost loved ones in this terrible outrage," a spokeswoman for the group said.
"Our aim in marking this dreadful tragedy is to provide a beautiful and fitting public and permanent memorial to the loss of so many innocent people."
People from 21 countries died when two bombs exploded in the Kuta area on 12 October, 2002.
