Carlisle Castle

Run your hand along the nearest wall. The stone is red sandstone, rough and slightly gritty, and in places it is worn smooth by weather and by centuries of shoulders brushing past. On a damp day the colour deepens to the shade of old brick. Listen too. Traffic hums somewhere behind you, but inside these walls the sound drops away. You are standing in the castle that guarded England's most fought-over frontier for more than eight hundred years.

This ground was a military site long before any castle stood here. Roman soldiers built a fort on this rise, part of the system linked to Hadrian's Wall, which ran just to the north. The Romans called the settlement Luguvalium. When you look out from the walls, you are looking across a landscape that armies have watched for nearly two thousand years. The river crossings, the flat land, the road north to Scotland. All of it mattered.

The castle itself begins in 1092. In that year the Norman king William the Second, often called William Rufus, marched north and took Carlisle. He drove out the local ruler and threw up a fortress, probably of earth and timber at first. It was a statement. This town, he was saying, belongs to England now. The Scots did not agree, and that argument would echo around these walls for the next six centuries.

The great stone keep in front of you came a little later, in the early twelfth century, under King Henry the First. A keep is the strongest tower of a castle, the final refuge if the outer walls fell. Here is the first surprise. For a time this English fortress was held by a Scottish king. David the First of Scotland controlled Carlisle in the mid twelfth century, strengthened the castle, and died here in 1153.

That back-and-forth defined the place. Carlisle sat on the border between two kingdoms, and the border moved. In 1315 Robert the Bruce, the Scottish king who had defeated the English at Bannockburn the year before, laid siege to the castle. His army brought siege engines and tried to storm the walls. The garrison, led by Andrew Harclay, held out. After about eleven days the Scots withdrew. The castle had done exactly what it was built to do.

Now climb into the keep, and look closely at the walls on the upper floor. Scratched into the stone are carvings, thought to date from the late fifteenth century. There are animals, figures, heraldic shapes, and small symbols. Many visitors walk straight past them. They are usually linked to prisoners or bored guards, men who had time on their hands and a sharp point to work with. It is a rare chance to see marks left by ordinary people, not kings.

The border here was not only a matter of royal armies. For generations the surrounding valleys were home to the Border Reivers, raiding families who stole cattle and settled feuds on both sides of the line. In 1596 one of them, William Armstrong, known as Kinmont Willie, was held in this castle. A band of Scottish riders led by Walter Scott of Buccleuch crossed the border at night and freed him. It was a humiliation for the English authorities, and the story was told in ballads for centuries.

The castle also held a more famous prisoner. In 1568 Mary, Queen of Scots fled across the border after losing her throne. She hoped her cousin, Elizabeth the First of England, would help her. Instead she was kept here under guard. It was the beginning of nearly two decades of captivity in England. The tower where she was lodged no longer survives, but this was the first of many places where she waited and wrote letters.

Look at the outer defences, especially the rounded artillery platform near the gatehouse. Its curved shape is often called the half-moon battery. It was added in the sixteenth century, in the reign of Henry the Eighth, when cannon had changed warfare. Medieval walls were built to stop ladders and arrows. Now they had to carry guns and absorb cannon fire. You can read that shift in the stone, from tall, thin walls to low, thick, rounded shapes.

In the English Civil War of the seventeenth century, the castle held out for the king. A Scottish army allied with Parliament surrounded the city, and the siege dragged on for months. Food ran out. Townspeople and soldiers suffered badly before the garrison finally surrendered in 1645. Then, a century later, came the last siege on English soil to involve this castle. In 1745 the army of Charles Edward Stuart, known as Bonnie Prince Charlie, captured it during the Jacobite rising.

The Jacobites, supporters of the exiled Stuart family, held the castle only briefly. Within weeks the Duke of Cumberland recaptured it, and Jacobite prisoners were crammed into its cells. Here is a story you will hear on site. In the dungeon, some stones are known as the licking stones. Local tradition says thirsty prisoners licked moisture from the damp walls to survive. It is a tale passed down rather than a documented record, but standing in that cold, dark space, it is easy to see why it lasted.

The castle never stopped being a working military site. For a long time it was the home of the Border Regiment, the local infantry regiment, and soldiers lived and trained in the barracks around the outer ward. That story is told in Cumbria's Museum of Military Life, inside the castle grounds. It covers more recent centuries, including both world wars. It is a reminder that this place sent men out to fight long after it stopped facing enemies at its own gate.

As you leave, turn back once more. Notice how the red stone of the keep sits above the newer barracks, the patched walls, and the tidy lawns. Every layer belongs to a different century and a different fear. Then look toward the city, where the cathedral rises in the same red sandstone. The castle and the town grew from the same ground. Carry that colour with you as you walk back across the road into Carlisle.
