Moving images of poppies were cast onto Shell Centre, and the London Eye was lit red for four nights to mark Remembrance Weekend.
On Friday morning pupils from St James Junior School in Kensington boarded the London Eye, accompanied by World War II Veteran Len Jeans, to pay their respects. At 11am, the wheel stopped moving and the children bowed their heads in an act of remembrance.
"We are delighted to support and salute the wonderful work of The Royal British Legion each year," said London Eye MD David Sharpe. "Marking Armistice Day with a Two Minute Silence is as important today as it has ever been."
The Royal British Legion GLA City Hall branch hosted the Armistice Day service, which was conducted by the branch chaplain Canon Richard Truss, vicar of St John's Waterloo. Hindu, Muslim and Jewish faith representatives also participated.
The chair of the London Assembly, Sally Hamwee AM, the Mayor of London, Ken Livingstone and Councillor Brian Coleman, vice-chairman of the London Fire and Emergency Planning Authority were among those to lay wreaths at the City Hall war memorial. This is the first time that this annual Remembrance Day service has been held at City Hall.
The National Maritime Museum commissioned artist Beth Derbyshire to produce 'Message'.
The piece involved 20 veterans of various conflicts. They began by signalling the message by semaphore from the roof of the Royal Observatory in Greenwich to other veterans at the Cutty Sark.
