The memorial will be a permanent reminder in the heart of London.

A memorial commemorating the 52 victims of the July 7 terror bomb attacks in London four years ago was unveiled in Hyde Park.

The Prince of Wales, Prime Minister Gordon Brown and Minister for London Tessa Jowell joined leading officials from the rescue services and survivors, families and friends of those killed in a moving ceremony.

The memorial is located in a secluded setting within London's Hyde Park and consists of fifty-two individually built-stainless steel columns; each representing a victim of the attacks; each three and a half metres tall.

Prince Charles said the date of the bombings 'would be etched vividly on all our minds as a brutal intrusion into the lives of thousands of people'.

He said:

'Everyone has their own way of responding to trauma, grief, injury, and bereavement but I do pray that all those touched by violence everywhere will eventually find peace again... above all I pray that they will gain comfort and strength from coming together to honour the memories of those taken from us, and in so doing commit ourselves to eliminating the circumstances that cause the violence in the first place.

I never fail to be amazed by the resilience and fortitude of the British people and it was this indomitable spirit together with the commitment passion and sheer doggedness of the emergency services that got us through that day and the weeks to come.'

The memorial will be a permanent reminder in the heart of London.
