All Hallows by the Tower Crypt: London’s Best-Kept Underground Secret
The Fascinating History Beneath the Floorboards
The church of All Hallows by the Tower was founded all the way back in 675 AD, making it three centuries older than the Tower of London itself. It has survived the devastation of the Blitz in World War II and miraculously escaped the Great Fire of London in 1666. But the true magic of this resilient landmark lies beneath your feet, buried deep within the dark atmospheric crypt.
The crypt itself was rediscovered during post-war reconstructions, revealing layers of history that span nearly two millennia. As you descend the stone steps, you are literally traveling backward through the timeline of human civilization. The air feels cool, the ambient noise of modern London fades to a dead silence, and the ancient stone walls begin to tell their stories.
