Queen Elizabeth II makes her final journey to London where she will lie in state for the public to pay their respects to the late monarch.
It comes after mourners in Scotland were able to pay their respects at Edinburgh's St Giles Cathedral.
But now the Queen's coffin will lie in state at Westminster Hall for four days before her majesty's state funeral on Monday, September 19.
Thousands and potentially millions are expected to visit the capital over the next few days, to pay their respects.
What and where is Westminster Hall?
The hall is nearly a thousand years old, dating back to 1099, and is the oldest building in the parliamentary estate of the Palace of Westminster.
It's been a part of key historic events including coronations, addresses from world leaders and the trail of Charles I.
