How can the public say goodbye to Queen Elizabeth?

STORY: The body of Britain's Queen Elizabeth will lie in state inside Westminster Hall in London.

where members of the public will be allowed to pay their respects

until the morning of the funeral on Monday, September 19.

‘’She's family and that, you know, I have to say goodbye as close as I can get."

Let's take a look at the arrangements and the lying-in-state tradition.

GFX: What is lying in state?

The body of a deceased person of significance is placed in a public building to allow the public to pay their respects.

It's a rare honor in Britain, previously accorded only nine other times,

mostly for royal family members, including Queen Elizabeth's mother in 2002.

The only non-royals who have lain in state were former British prime ministers William Gladstone and Winston Churchill

as well as the victims of an airship crash in 1930.

GFX: Lying in state for Queen Elizabeth

During the lying-in-state period, Queen Elizabeth's coffin will be closed

and rest on a catafalque.

Members of the public will be allowed to file past the catafalque from 4 p.m. GMT on Wednesday, September 14

until 6:30 a.m. on Monday, September 19, the day of the funeral.

The lying-in-state will be open 24 hours a day.

The government is preparing for a very long queue, with hundreds of thousands of people expected to attend.

Vanessa Nanthakumaran was first in line.

"When I enter there (to see coffin lying in state) it is going to be, it will be very emotional. It's going to be such a moment it'll be sombre.''

GFX: Security arrangements

Visitors will go through airport-style security.

Only one small bag per person is permitted.

No food, liquid, banners or flowers will be allowed…

and the public is advised to dress ‘appropriately’ and not take any pictures.

"We came down on Thursday so that we could be ready for the funeral, yeah, and it's important because everybody loved the Queen. Everybody. Not just the country, but the world."

The Times reported that some 10,000 police officers will be deployed in London

and army bomb disposal teams will be on standby.

Police are on alert not just for terrorism-related incidents

but for protesters such as environmental activists.

After the funeral, the Queen’s coffin will be taken to Windsor Castle.

There it is expected to be lowered into the royal vault and interred in the King George VI Memorial Chapel,

where the queen's parents and sister are buried.
