The memorial features one pillar for each of those killed in the bombings
Families of the victims of the 7 July 2005 London bombings have praised a permanent memorial created in their honour in Hyde Park.
Fifty-two people died and hundreds more were injured when four suicide bombers detonated backpacks at separate locations on public transport.
The memorial consists of 52 stainless steel pillars, each 3.5m (11.5ft) tall, grouped to represent the four attacks.
Members of the bereaved families group have said it is a "fitting tribute".
A plaque alongside the pillars - described as stelae - lists the names of those killed in the bombings.
'Enormity of loss'
A group representative said the memorial - close to the park's Lover's Walk - would ensure they were never forgotten.
"It represents the enormity of our loss, both on a personal and public level.
"We hope this memorial will speak to visitors, so they can understand the impact of these horrific events."
The bombers struck aboard Tube trains near Edgware Road, King's Cross and Aldgate and on the number 30 bus at Tavistock Square, all in central London.
Behnaz Mozakka, 47, a biomedical officer, was killed on a Piccadilly line train near King's Cross station while commuting to work.
Her daughter Saba Mozakka, one of six family members to sit on a liaison board during the memorial's design process, described the finished product as "truly incredible".
"I'm very happy. It's very poignant," said the 28-year-old from Finchley, north London.
"It's an amazing tribute to my mum and the 51 others who were so viciously and brutally taken from us."
Ms Mozakka said she hoped people would feel passionate about the memorial when it is officially unveiled on Tuesday.
The open casting process used to create the columns means that although each is made using an identical mould, the finished product is unique.
Each features an inscription bearing the date, time and location of the bombing it represents.
