The story
Take a moment to look up and let your eyes trace the rugged, honey-colored stones rising above the corner of Ship Street and Cornmarket. You are standing before a true survivor. This is the Saxon Tower of St Michael at the North Gate, and it is the oldest building in all of Oxford.
While the prestigious university colleges nearby were founded in the centuries that followed, this tower was already ancient when the first scholars arrived. It has stood right here since roughly the year 1040, back when England was ruled by Edward the Confessor and the Norman Conquest was still a generation away. If you look closely at the windows near the top, you can see the distinctive double openings separated by small stone pillars, known as baluster shafts.
This is classic Anglo-Saxon architecture, built with a sense of urgent permanence. For nearly a thousand years, this tower served a dual purpose: it was the bell tower for the church of St Michael, but more importantly, it was a vital part of the city’s defenses. This very spot was the site of the North Gate, the strongest and most important entrance to the walled city of Oxford.
Imagine the scene a millennium ago. The bustling shopping street you see today was a muddy track leading to a massive fortified gateway. Deep defensive ditches, known as the Canditch, ran right where Broad Street is now.
As a traveler, you would have had to pass under the shadow of this tower to enter the safety of the city. By the sixteenth century, the gateway had evolved into the notorious Bocardo Prison. If you look at the tower's base, try to visualize the grim cells that once leaned against its walls.
This is where the famous Oxford Martyrs—Bishops Latimer and Ridley, and later Archbishop Thomas Cranmer—were imprisoned during the reign of Queen Mary Tudor. In the 1550s, they were led from the darkness of this gate to be burned at the stake just a short walk away on Broad Street. Today, the actual cell door that once held them is preserved inside the tower.
In 1771, the Great North Gate was finally demolished to make way for modern traffic, leaving the Saxon Tower standing alone, a solitary sentinel of a vanished fortification. As you continue your journey, remember that while the city walls have mostly crumbled and the gates have disappeared, these stones remain. They have watched the transition from a Saxon stronghold to a medieval center of learning, surviving fires, civil wars, and the relentless march of time, still guarding the memory of the old North Gate.
