Look above Buckingham Palace and the flag can tell you something a palace window cannot. When the Royal Standard flies there, the sovereign is in residence. When the familiar red, white and blue Union Flag is flying instead, the King is elsewhere. The difference is easy to spot once you know what to look for.
The Standard also follows the monarch beyond the palace. It may fly at an official building during a visit by the King, on his car during official journeys, and on aircraft while they are on the ground. It is a sign of the monarch’s presence, not a general decoration for a royal occasion.
Two flags, two meanings
Royal Standard: Look for gold lions and a harp on red, gold and blue panels. It marks the sovereign’s presence and stays at full mast.
Union Flag: Look for the red, white and blue crosses. It is the national flag, and it can be lowered in mourning.
Why there are lions and a harp
The Royal Household’s guide explains that the design used in England is divided into four sections. The three gold lions of England appear twice, a single red lion represents Scotland, and a gold harp on blue represents Ireland. In Scotland, the arrangement changes: the Scottish lion takes the two positions held by England’s lions in the other version.
There is no Welsh dragon on the Royal Standard. The Household traces that absence to the history of the royal arms: Wales had already been recognized as a principality before the Scottish and Irish arms were incorporated. The flag preserves that heraldic history, which is why it doesn’t read like a modern map.
Why the Standard never flies at half-mast
The Standard stands for the continuity of the Crown. A monarch’s successor takes the throne immediately, before any public proclamation or coronation. That’s why the government’s mourning guidance after Queen Elizabeth II’s death in September 2022 said the Royal Standard would not be lowered to half-mast, while Union Flags at royal residences would be.

This can look unfamiliar to American visitors, who may associate a flag at half-staff with the death of a head of state. In Britain, the national flag can signal public mourning while the sovereign’s banner follows its own rule. That distinction helps explain why footage of a royal residence can show a flag at full height even during a period of national grief.
If you’re following a procession, the flag is one of several clues to what you’re seeing. Our look inside the Royal Mews explains the horses and carriages that make those public occasions possible, and our House of Windsor family tree helps put the people in the picture.
