Thousands of mourners have lined the streets from Buckingham Palace to Westminster Hall to catch a glimpse of Her Majesty Queen Elizabeth’s coffin

Her Majesty was brought in a procession with Princes William and Harry, and their father King Charles the third walking behind.

The Queen will lie in state until 6:30 am BST on Monday morning, the day of her funeral.

Members of the public now have the opportunity to line up and pay their respects to the late monarch, filing through the grand old building that is Westminster Hall.

Constructed in 1097, the building is a cornerstone of British history.

It has played host to the trials of Charles the first, Henry the eight’s coronation banquet, and speeches by Nelson Mandela, French President Charles de Gaulle, Pope Benedict, and Barack Obama.

During this lying-in-state period, Westminster Hall will be open for 24 hours a day, with the Queen’s coffin left closed and resting on a raised platform.

It is draped with the Royal Standard flag, and topped with the Imperial State Crown, orb and sceptre.

Hundreds of thousands are expected to file past.

There are currently queues of more than three kilometres along the South Bank of the river Thames.

As Her Majesty was brought through the city, guns could be heard from Hyde Park, while Big Ben was rung every minute.

Mourners reflect on their beloved Queen.

The Queen’s funeral will be held on Monday September 19, which will be a bank holiday for the United Kingdom.
