When travelers picture London, they often think of the Union Jack waving atop royal palaces and red phone boxes. But that’s the flag of the United Kingdom, not London itself. In reality, London has its own official flag—one with medieval roots, religious symbolism, and more than a little confusion. In this blog, we break down the design, meaning, and myths surrounding the London flag, so you’ll know exactly what you’re looking at next time you spot it flying in the city.

🏛️ What Is the Official Flag of London?
The official flag of the City of London (the historic core of modern London) features:
- A white background
- A bold red cross (St. George’s Cross)
- A red sword in the top left corner (hoist side)
This flag represents the City of London Corporation, which governs the one-square-mile area that houses the financial district and historic landmarks like St. Paul’s Cathedral and the Tower of London.

⚔️ What Does the Sword Represent?
The red sword in the top left corner isn’t decorative—it holds deep meaning.
- It symbolizes St. Paul, the patron saint of the City of London.
- According to tradition, he was martyred by beheading, which is why the sword points upward.
- St. Paul’s Cathedral (a major London landmark) is dedicated to him.
This subtle but powerful addition separates the City of London flag from the flag of England, which only features the red cross.
📜 How Old Is the London Flag?
The flag’s design dates back several centuries, with records of its elements appearing as early as the 13th century. Though it wasn’t officially codified until more recently, its usage has been long associated with civic pride, religious symbolism, and local governance.

Understanding the difference is key to decoding London’s visual identity.
🧠Why the London Flag Still Matters
