Queen Elizabeth sat alone, dressed in black and with her head bowed, in the pews of St. George's Chapel as she mourned her husband, Prince Philip, during his funeral on Saturday.

The poignant image was one of many touching moments throughout the funeral of the Duke of Edinburgh, who died at the age of 99 on April 9, BBC News reported on Sunday.

Prince Charles' grief was also evident during the emotional scenes. He looked tearful as he viewed the sea of tributes to his father. He was pictured at the funeral alongside other royal family members.

At one point, a visibly distraught Sophie, Countess of Wessex, removed her face covering to wipe her tears.

After the close of the hour-long ceremony, Prince Harry and Prince William -- who were reunited at the funeral for the first time in more than a year -- could be seen walking and chatting together.

The Queen's family said Philip's death left a "huge void" in the queen's life. Prince Philip was the Queen's "strength and stay."

Philip was honored at Windsor Castle in a ceremony steeped in royal and military tradition but also infused with his own personality.

The Duke's coffin was draped in his personal flag. It represents elements of his life, from his Greek heritage to his British titles.

Numerous military-led honors also gave the day a personal dignity, from saluting royal guards to trumpeters. Philip served in the Royal Navy during World War 2.

Coronavirus restrictions in the UK mean only 30 people are allowed to attend funerals and observe social distancing protocols.

The guest list includes members of the Queen and Duke of Edinburgh's families, including three of his German relatives.

Philip's coffin was placed on a modified Land Rover that the prince himself helped design.

The Band of the Genadier Guards led the procession, followed by military leaders. The coffin paused for the national minute of silence at 3 p.m. (AEST).

The period of national mourning ends on the day of the funeral. A gun fired from the East Lawn signified the start and end, as a bell tolled in the Curfew Tower, according to BBC.

The Royal Family will continue to observe mourning for another week. "There is a desire for some privacy," a Buckingham Palace spokesperson said.
