To spot Oxford Castle, just look ahead for a mighty, rugged stone tower rising above the green trees, standing tall by the edge of the water-St George’s Tower is the clue you can’t miss.
Now, as you stand here, take a moment to imagine the echoes of nearly a thousand years swirling around this place. If you listen closely, you might just hear the distant clang of hammers striking stone, or perhaps the slosh of water in the moat that once surrounded the castle. This spot began as a wooden fort in the 1070s, built by a Norman baron named Robert D’Oyly after he marched in with William the Conqueror. Oxford, battered from the invasion, needed protection-and what better way than to drop a huge castle, right by the town’s old west gate, and dig out a moat using the stream off the Thames? Talk about making a dramatic entrance!
But D’Oyly wasn’t messing around. Soon enough, the wood gave way to stone, and the castle swelled in size. Picture a huge motte-a steep mound-topped by a stone keep, with thick curtain walls that now looped right around the still-surviving St George’s Tower behind you. This tower likely predates even the castle itself; it may have kept watch over the Saxon west gate, long before the Normans set foot here. For a tower so old, it’s hardly had a quiet life. In times of war, it saw armies come and go and, at least once, a daring nighttime escape!
Let’s go to the winter of 1142, in the middle of a brutal civil war known as the Anarchy. Empress Matilda, cloaked all in white, found herself surrounded by King Stephen’s army. The city was captured, and supplies at the castle ran dangerously low. One snowy night, with the castle mill stream frozen solid, legend says Matilda and a handful of knights slipped out, blending into the snow like ghosts, right under the noses of Stephen’s men. Whether she used a secret gate or simply clambered down the walls, it was the ultimate medieval jailbreak.
As centuries drifted by, the castle traded swords for cells. Its military power faded after the 1300s-no more kings or queens holding court-and by the 18th century, the space was used mostly as a prison and for county business. The surviving square keep, the round tower built in the 1200s (sometimes called ‘Henry III’s Tower’), and the echoing crypt beneath St George’s Tower are all that’s left of its original medieval heart. By now, you might be wondering about life inside those grim old prison walls. Imagine the clang of the old gates, the heavy air thick with whispers and the scuffle of prisoners’ feet. Not exactly anyone’s idea of a cozy long weekend!
During the 1700s, prison reformer John Howard came by and didn’t like what he saw-rats, overcrowding, and far too many hard times. Some rather drastic changes followed. The old chapels were knocked down, and part of the crypt beneath St George’s Tower was carefully rebuilt. Over all this time, the keep was largely demolished and the sloping green mound you see is what remains of that mighty motte.
Oxford’s castle even played host to all sorts of fascinating events: county courts, grand juries, executions, and even a deadly plague that wiped out nearly an entire courtroom in what became known as the ‘Black Assize’ of 1577. With that much drama, you’d think the castle might be ready for a quiet retirement-but far from it!
In the centuries that followed, the castle’s prison grew and modernized. It held everyone from hardened criminals to a seven-year-old girl found guilty of stealing a pram-clearly, Oxford didn’t mess around. But by 1996, the time of dungeons and cells was finally up, and the prison shut its doors. Today, instead of prisoners, it welcomes visitors eager for tales from the past. You can even sleep in the old cells, as many have now become hotel rooms-talk about a room with a history!
So, as you stand beside these weathered stones on the riverbank, imagine armies clashing, secret escapes, royal courts, and centuries of whispered stories drifting through the cracks. The stones of Oxford Castle have seen it all-from swirling medieval snow to the gentle footsteps of modern travelers like you. Don’t forget to look up and wonder: who was looking back down at you from that tower a thousand years ago?
