The Queen marks her 90th birthday with the pomp and pageantry of Trooping the Colour

The Queen's official birthday celebrations were made extra special this year as Her Majesty celebrated turning 90. On Saturday (June 11), the monarch was smiling widely as she attended the annual Trooping the Colour ceremony – an event that's seen her front and centre every year of her reign, except in 1955 when it was cancelled due to a national rail strike.

Looking as bold as ever at the 64th parade, the Queen was the focus of all attention in a bright-green coat and dress by Stewart Parvin.

She was supported by her husband Prince Philip, who travelled with his wife in The Queen's Carriage from Buckingham Palace. The 95-year-old duke donned his bearskin cap and uniform of the Colonel Grenadier Guards.

The Duchess of Cornwall, the Duchess of Cambridge and Prince Harry were the first members of the family to leave, riding in the Barouche carriage. Kate was resplendent in her Alexander McQueen coat, while Harry donned his Household Cavalry Number 1 ceremonial with Forage Cap.

Meanwhile, other members of the royal family rode on horseback. Prince William rode on a grey charger Wellesley, who he usually rides for the parade, while Prince Charles and Princess Anne rode on George and Elizabeth respectively.

Trooping the Colour takes place every year on a Saturday in June at Horse Guards Parade. The royals make their way down the Mall to Horse Guards Parade, accompanied by more than 1,400 soldiers and 200 horses. Over 400 musicians from different bands and corps of drums all march and play as one.

Steeped in tradition, the impressive display of pageantry involves the Queen inspecting the line of guards including her personal troops, the Household Division.

The colours, or flags, of the battalion are carried – in other words, "trooped" – down the ranks. This year the Queen's Colour of the Number 7 Company Coldstream Guards is being trooped.

After, the royals rode back in their carriages to Buckingham Palace via Whitehall. Members of the royal family headed up to the palace balcony so they could greet the Queen and Prince Philip as they pulled into the palace.

Shortly after one o'clock, the Queen and the royal family watched an RAF flypast from the balcony. Gun salutes were also fired in Green Park and other cities across the UK.
