It’s not immediately obvious what this series of upright stainless steel pillars standing on the eastern edge of Hyde Park has been placed there for.

But look a little closer and you’ll see inscribed upon a date which any long-term Londoner immediately recognises – 7th July, 2005: the day when a series of bombs claimed 52 lives on three trains and a bus at various locations around central London.

The memorial, designed by architects Carmody Groarke and engineering team Arup working in consultation with victims’ representatives, Royal Parks and the Department for Culture, Media & Sport, consists of 52 pillars – one for each victim of the bombings.

The 3.5 metre high, 850 kilogram pillars are clustered together in four groups representing the four locations of the bomb attacks – Tavistock Square, Edgware Road, King’s Cross and Aldgate. They are marked with the times, dates and locations of the bombings and there’s also a 1.4 tonne stainless steel plaque upon which are written the names of the victims located nearby.

The RIBA award-winning memorial, which is located just to the north of the colossal statue Achilles and Hyde Park Corner, was unveiled by Prince Charles and Lady Camilla on the fourth anniversary of the attack in 2009.
