A monument commemorating the 9/11 tragedy was unveiled this week, after a five-year search to find it a permanent home.
Mayor Boris Johnson, historian Simon Schama and US ambassador Matthew Barzun were present as the 28-ft high sculpture, made from steel taken from the ruins of the World Trade Centre, was displayed at the Queen Elizabeth Olympic Park in east London.
Mr Johnson said: "We need to remember 9/11 in all its horror if we are truly to appreciate the values that were under threat that day."
The sculpture was commissioned in 2010 by SINCE 9/11, an educational charity chaired by Jewish businessman and JC columnist, Peter Rosengard.
