On Thursday, high ranking members of the Royal Family joined the Queen on her Buckingham Palace balcony as they watched over the Trooping the Colour ceremony, as well as the Red Arrows display. It's possibly the most famous balcony in the world with royals having gathered on the balcony since 1851 to celebrate weddings, birthdays and to commemorate important wartime events. It was Queen Victoria who first started the tradition during the celebrations of the Great Exhibition over 170 years ago.
