Claire Lomas, who completed the London Marathon in a bionic suit, lit the Paralympic cauldron in Trafalgar Square this morning. The flame had come from England's highest point Scafell Pike where it was lit on Wednesday.
Next week, the flame will be combined with three others from Scotland, Wales and Northern Ireland before being taken to Stratford for the Paralympic Games opening ceremony on Wednesday.
The Paralympic relay made a pop stop off to visit Abbey Road in St John's Wood, north-west London.
The Paralympic Flame has arrived in London ahead of tonight's opening ceremony.
