Hexham Gaol, said to be the oldest purpose-built prison in the United Kingdom. It’s currently a prison museum.

Most medieval prisons were afterthoughts. A castle had a cellar, a gatehouse had a spare room, and a town had a lock-up in the wall, and that was where you put people until a court decided what to do with them. Hexham is different. In 1330 the Archbishop of York ordered a building put up in this Northumberland market town for one purpose only: to hold prisoners. It still stands on Hallgate, a squat tower of grey stone opposite the Moot Hall, and it is generally accepted as the oldest purpose-built prison in England.

A bishop’s own country

To understand why an archbishop needed a prison, you have to understand Hexhamshire. From the early Middle Ages, the land around Hexham did not follow the same governance as the rest of Northumberland. It was a liberty, later called a regality, belonging to the Archbishops of York, who traced their claim back to the illustrious Saxon abbey founded here by Wilfrid in AD 674. Within its boundaries the archbishop was effectively the lord: he held the courts, appointed the officers, took the fines, and answered to the king only at a distance.

Running a liberty meant running justice, and justice needed somewhere to keep the accused. Archbishop William Melton, who held York from 1317 to 1340, was a practical administrator with a long memory for money owed. In 1330 he ordered the construction of a gaol at Hexham, and builders finished the work by 1333. The town already had a place for hearing cases: the Moot Hall, a fortified gatehouse on the edge of the Marketplace where the archbishop’s bailiff sat in court. The new jail went up a few yards away so that a prisoner could be walked from the cells to the courtroom and back in minutes.

The stone did not have to come far. Four miles east, at Corbridge, lay the abandoned Roman town of Coria, and Hexham had been quarrying it for centuries. Wilfrid’s masons had used Roman blocks for the abbey crypt in the seventh century, and the town’s later builders followed their example. Walk around the outside of the Gaol today and you will find reused Roman stone in its walls, just as you will in the crypt a few hundred yards away.

What the building was for

The Gaol is a rectangular tower of four levels. The ground floor and the floors above housed prisoners who could pay for their keep and the gaoler who ran the place. Below ground was the dungeon, a stone chamber with no natural light, reached through a trapdoor in the floor above. This was where the poorest prisoners went and where, by every account that survives, life depended on charity. A medieval gaoler was not a salaried public servant in the modern sense; he was a man who had bought or been granted the right to run the prison, and he made his living from fees. Prisoners paid for food, for bedding, for lighter irons, and for the privilege of a room with a window. Those who could not pay lived on what their families brought, what the town’s religious houses gave, and what they could beg through the bars.

It is worth being clear about what a medieval gaol was not. It was not, in the main, a place of punishment. The idea of imprisonment as a sentence, with a fixed term to be served, belongs to a later age. In the fourteenth century you were held in gaol while you waited for the bailiff’s court, for the archbishop’s justices on their circuit, for a debt to be paid, or for a fine to be settled. Punishment, when it came, happened elsewhere and in public: the pillory in the Marketplace, the whipping post, and the gallows. The Gaol’s job was to keep you until then and to profit from you while it did.

The Reivers

For most of its working life, the Gaol’s most famous inmates were the Border Reivers. From the late thirteenth century to the early seventeenth, the land on both sides of the Anglo-Scottish frontier was raided by families who made their living from cattle theft, blackmail (a word the Borders gave to the English language), kidnapping and feud. The Armstrongs, Elliots, Charltons, Robsons, Milburns and Dodds rode by night, took what they could, and retreated into valleys where no sheriff cared to follow. Hexham, on the Tyne at the southern edge of this country, was both a target and a place of judgement.

Reivers caught in Hexhamshire ended up in the Gaol, and the records that survive show the archbishop’s officers dealing with them in bulk. In the sixteenth century the liberties’ courts were still sending men from Tynedale and Redesdale down through the trapdoor, and the names in the rolls are the names still painted over shop doors in the town. The Gaol’s museum today devotes much of its space to the Reivers, and it is the right choice: nowhere else in England can you stand in a building that held them.

The end of the liberty

The archbishop’s private country did not survive the Tudors. Hexham Priory was dissolved in 1537, its last prior hanged for his part in the Pilgrimage of Grace, and in 1572 an Act of Parliament under Elizabeth I annexed Hexhamshire to Northumberland, ending the archbishops’ regality after nearly nine hundred years. The Gaol carried on regardless. It passed to the Crown and then, in effect, to the county, and it kept receiving prisoners through the seventeenth and eighteenth centuries, by which time it had become cramped, insanitary and hopelessly out of date. It finally closed in 1824, almost five hundred years after Melton’s masons finished it, when a new House of Correction took over its work.

Thereafter, it became what old buildings become: a store, a bank vault, a solicitor’s office, and a place people walked past. In the twentieth century it was restored and opened as a museum, and today a glass lift carries visitors down through the floors to the dungeon, which is still the most affecting room in the building. It is small, cold, and completely dark without the lights. For seven hundred years, it held people.

Why it matters

Hexham Old Gaol is not a grand monument. It is a working building that happened to survive, and that is precisely why it is valuable. Castles and cathedrals tell us how medieval power liked to present itself. The Gaol tells us how it actually operated, day to day, on the men and women at the bottom: who paid, who starved, and who waited in the dark for a court that might not sit for months. It is the medieval state at its most ordinary and its most honest. If you are ever in Northumberland, go and stand in the dungeon for a minute, then walk to the Moot Hall and think how short that journey was for those in irons.
