Today marks ten years since four suicide bombers targeted the rush hour and killed 52 people, injuring 700 more. A decade on, we'd like to hear your thoughts and memories about that day. Londoners responded to the bombings with a typical determination that we wouldn't let fear change the way we live. For most of us, today will be business as usual. But it's also a memorial day, when Londoners will remember what happened, where we were and who helped - and celebrate a city which we're proud of, because it remains open and tolerant.
To help do that, we talked to some Londoners who were profoundly involved in those tragic events. Read their inspiring stories in today's magazine and on the blog throughout the day, and please share your own memories with us below or tweet us at @timeoutlondon.
Today's memorial service at St Paul's will be broadcast live on BBC1 from 10.30am. There will be a minute's silence across London at 11.30am. A memorial service open to the general public will be held in Hyde Park from 2.30pm.
