The Ancient Ceremony That Has Happened Every Night in London for 700 Years

Sharing is caring!

Every night at exactly 9:53pm, a Yeoman Warder steps out of the Byward Tower at the Tower of London, carrying a lantern and a set of keys. The gates are locked. A bugler plays the Last Post. And it is done — just as it has been done every single night for more than 700 years. Through plague, through fire, through two world wars, this ceremony has never stopped. And most visitors to London never even know it exists.

What Happens at the Ceremony of the Keys

The Ceremony of the Keys is, by most accounts, the oldest military ceremony in the world. It begins each evening in near-silence, watched by a small group of lucky visitors standing in the same cobbled courtyard where some of England’s most famous prisoners once waited for dawn.

The Chief Yeoman Warder — dressed in Tudor uniform, lantern in hand — collects the escort of soldiers and begins the locking of the outer gates. Each gate is closed and secured in turn. The whole ritual takes under half an hour.

At the Bloody Tower archway, a sentry challenges the approaching party. The exchange is always the same:

“Halt! Who comes there?”
“The keys.”
“Whose keys?”
“King Charles’s keys.”
“Pass, King Charles’s keys. All’s well.”

Only one word ever changes — the name of the monarch. Everything else has remained the same, word for word, for centuries.

The Night a Bomb Couldn’t Stop It

The most remarkable thing about the Ceremony of the Keys is its continuity. In all of recorded history, it has been interrupted only once — during the Second World War, when a German bomb exploded close enough to knock the Yeoman Warder escort off their feet.

The ceremony was delayed. The Chief Yeoman Warder wrote to King George VI to apologise. The King replied that, given the circumstances, he considered the lapse quite understandable.

It resumed the following night. And every night since.

That level of unbroken continuity is almost impossible to comprehend. The ceremony was already ancient when Shakespeare was writing. It was already old when the Tudors were building their palaces. Somewhere in that lantern-lit walk across the cobblestones, you can feel the full weight of the city beneath your feet.

The Tower After Dark

The Tower of London is not simply a tourist attraction. It remains a working royal palace and garrison, occupied by the Yeoman Warders — the famous Beefeaters — and their families. Ravens still live within its walls. According to legend, if the ravens ever leave the Tower, the Crown and the Kingdom will fall. The six resident ravens are therefore fed each morning and their wings are carefully trimmed.

Standing here after dark, once the day’s crowds have gone, is an entirely different experience from any daytime visit. The floodlit White Tower — built on the orders of William the Conqueror in the 1070s — turns a pale gold against the night sky. The Thames moves silently beyond the outer walls. The cobblestones are uneven underfoot, worn smooth by centuries of boots.

Anne Boleyn walked these stones. So did Thomas More, Lady Jane Grey, and the two young princes who vanished inside these walls in 1483 and were never seen again. The Tower held Britain’s Crown Jewels, its royal mint, its menagerie of exotic animals, and its most important prisoners — often simultaneously.

How to Actually Get Tickets

Here is where most visitors stumble. The ceremony is open to the public — and it is entirely free. But you cannot simply show up on the night. The Tower admits only a small number of people each evening, and advance application is required.

To apply, write to the Ticket Office at HM Tower of London, London EC3N 4AB. Include the dates you would like to attend, the number in your party, and a stamped addressed envelope for the reply. Applications are processed in order of receipt and availability is limited, so apply as early as you can — ideally several weeks before your visit.

Gates open for ceremony guests at around 9:30pm. You will be admitted as a group and escorted to the viewing position. Photography is permitted, though without flash. The ceremony ends at approximately 10:05pm and you are then escorted out.

Very few visitors to London ever see this. Those who do tend to remember it for the rest of their lives.

Making the Most of Your London History

The Tower of London sits at the eastern edge of the City, a short walk from London Bridge. If you are drawn to the kind of London that most tourists never find, there is more of it close by. Just minutes from the Tower, Londoners walk past Roman ruins that have been standing since the first century — fragments of the ancient city wall that once enclosed Londinium, still embedded in the fabric of the modern streets.

If you are building a trip around London’s most atmospheric and historic corners, our one-week London itinerary maps out a route that moves between the famous and the genuinely hidden — including the parts of the city that most tourists never reach. And when you are ready to start planning from scratch, the London travel planning guide covers everything from when to go to where to stay.

The lantern moves through the dark. The gates close. And London — as it has done every single night for seven hundred years — locks itself in for the night.
