When Deborah and I visited Blackness Castle and Lochleven Castle in June 2026, their prison stories felt very different. Blackness was a royal state prison built into a formidable fortress beside the Firth of Forth. Lochleven was an island stronghold where Mary, Queen of Scots lived under guard in rooms that were far removed from the castle’s cramped bottle dungeon.
These are two examples of Scottish castle dungeons, but the phrase can be misleading. Scotland’s castles confined captives in everything from rock-cut pits to furnished tower rooms. The surviving spaces at Edinburgh, Blackness, Stirling, St Andrews, Lochleven, Dirleton, and Rothesay show how imprisonment reflected status, politics, architecture, and each castle’s needs.

What Were Scottish Castle Dungeons?
Popular culture encourages us to imagine every dungeon as a dark underground chamber fitted with chains. Some Scottish castles did contain severe pits reached through openings above, but “dungeon” is now used loosely for several kinds of prison space.
A castle might hold a high-ranking political captive in a private chamber while confining a prisoner of lower status in a vault or pit. Military prisoners could occupy adapted barracks or storerooms. A hostage might be treated according to rank because the captor expected a ransom, negotiation, or political advantage. Comfort did not make that person free.
This variety matters to heritage travelers. A label such as prison, pit, vault, guardroom, or bottle dungeon gives clues about the original space. So do fireplaces, windows, latrines, wall plaster, stairs, and the method of entry. Together, they help us move beyond the theatrical dungeon and consider the daily reality of confinement.

How Can You Tell a Dungeon From a Cellar?
Castle rooms changed purpose over time. A secure basement used for food, drink, weapons, or valuables could later hold prisoners. Conversely, a room now called a dungeon may have limited documentary evidence for that use. Good site interpretation usually combines the building’s physical features with written records, archaeology, and comparisons with similar structures.
A purpose-built or strongly identified prison may have a restricted entrance, few openings, evidence of bars, or a position that made escape difficult. Bottle dungeons narrow toward the top, like a bottle’s neck, and are entered from above or through a tight opening. A rock-cut prison relies on the natural bedrock as part of its enclosure.
The safest approach is to follow the evidence presented for each castle rather than applying one definition everywhere. That makes the seven sites below more interesting, not less. Each preserves a different relationship between custody and castle life.
Prisoners, Hostages, and State Power
Castles were residences, administrative centers, arsenals, and military positions. Their prison spaces served those roles. Kings and royal officials used strongholds to hold political opponents, religious figures, nobles who had fallen from favor, prisoners of war, and people awaiting judgment.
For family historians, these places suggest useful records. Prisoners might appear in government correspondence, treasury accounts, military papers, court proceedings, kirk records, or local burgh documents. A castle visit cannot prove an ancestral connection, but it can explain the institutions and power structures surrounding a documented life.
Scottish Castle Dungeons: Edinburgh and the Forth
Edinburgh Castle
Edinburgh Castle’s best-known prison spaces belong largely to its military history. Vaults beneath the later great hall were adapted for prisoners of war, particularly during eighteenth- and early nineteenth-century conflicts. Displays interpret the crowded conditions and the marks prisoners left behind.
This is not a simple medieval pit. It is a prison complex within a working fortress, where confinement, supply, discipline, and international warfare met. The surviving graffiti is especially valuable because it brings individual hands into a story usually told through governments and armies.

Edinburgh Castle also provides a useful starting point because it shows how prison use could continue long after a castle’s medieval domestic role had changed.
Blackness Castle
Blackness Castle stands on the south shore of the Firth of Forth, its long plan often compared to a stone ship. Its central tower served as a state prison, while the harsher stem tower contained lower-status prison rooms. The castle’s official history describes a site that became a royal castle, garrison fortress, state prison, and ammunition depot.
Our Visit
When Deborah and I returned on June 11, 2026, light rain made the exposed rock and courtyard shine. This was our second visit, and the courtyard remained the most memorable part for me. Its irregular bedrock, high walls, stairs, doorways, and towers reveal how the fortress was fitted around the shore rather than laid out as a comfortable palace.

The interpretation panels explained a striking hierarchy. Important captives in the central or “mast” tower could occupy rooms with fireplaces and windows. Some brought servants, books, furniture, silver, and wall hangings. Cardinal David Beaton, Archbishop of St Andrews, was confined there for several months in 1543. At the other extreme, lower-status prisoners in the stem tower faced a cold pit where water could enter with the tide.

Contrasting Imprisonments
That contrast is the heart of Blackness’s prison story. Imprisonment depended not only on the offense but also on rank and political value. A privileged captive might move within limits and maintain a household, while another person endured a far more severe enclosure only a short distance away.
Blackness also carries a modern screen association. Deborah and I stood in the courtyard area used for Jamie Fraser’s flogging scene in Outlander. The filming connection was memorable, but the documented prison spaces were more revealing because the interpretation showed how custody actually worked within the castle.
Stirling Castle
Stirling Castle demonstrates why prison terminology requires care. Men involved in the Radical Rising of 1820 were held in cells associated with vaults beneath James V’s palace. John Baird was reportedly kept separately in a space described in contemporary discussion as the dungeons, although the precise room identification requires caution.
The episode belongs to a much later Scotland than the medieval royal court most visitors associate with Stirling. It reminds us that old castle spaces could be reused by changing governments. A storeroom, vault, or service area could become a secure place of detention when political unrest demanded it.
Scottish Castle Dungeons: Fife and Kinross
St Andrews Castle
St Andrews Castle contains one of Scotland’s clearest examples of a bottle dungeon. The narrow opening leads to a deeper rock-cut chamber whose shape made exit extremely difficult without help from above. Its physical form communicates confinement immediately, even before a visitor reads the history.

The site is inseparable from the Scottish Reformation. Protestant preacher George Wishart may have been held in the dungeon before his execution in 1546, although that detail is not certain. Cardinal David Beaton’s body was placed there after he was murdered in the castle later that year. Historic Environment Scotland’s account of the castle explains the subsequent siege, during which defenders and attackers dug opposing mine passages beneath the walls.
Those events show why the bottle dungeon should not be treated as a detached curiosity. It formed part of an archbishop’s fortified residence during a struggle involving religion, royal policy, foreign alliances, and local power. The chamber is small, but the conflict surrounding it reached far beyond St Andrews.
Lochleven Castle
Lochleven Castle occupies Castle Island in Loch Leven, and the boat journey is part of understanding the site. When Deborah and I visited from Fife on June 5, 2026, the day was sunny but windy. The water was choppy, and getting on and off the boat was a little tricky. As the tower came into view across the loch, the island setting made its value as a prison immediately clear.

Mary, Queen of Scots
Mary, Queen of Scots was imprisoned at Lochleven from June 1567 until her escape in May 1568. She was forced to abdicate in favor of her infant son, James VI. Mary spent most of her confinement in upper rooms of the main tower, accompanied by women from the Douglas household. She was not lowered into the bottle dungeon.
Inside the tower, modern staging made movement through the surviving levels easier. The deep window alcoves with stone seating stood out to us. Those details helped me imagine the tower as a residence as well as a place of custody. Its upper rooms once offered more comfort than their roofless condition suggests today, but the surrounding water and guarded landing still restricted Mary’s choices.

Bottle Dungeon
The castle’s separate bottle dungeon is reached through a narrow opening and represents a different grade of confinement. Our photographs confirm that we looked into this dark chamber, even though I did not remember its name afterward. Seeing both spaces is useful: Mary’s politically sensitive captivity and the dungeon’s physical severity should not be merged into one story.

Mary’s Escape
Mary escaped on May 2, 1568, with help from Willie Douglas. The plan depended on keys, signals, a boat, and assistance on the mainland. Crossing to the island helped us understand why escape was difficult and why cooperation from within the household was essential.
Dirleton Castle
Dirleton Castle in East Lothian preserves a rock-cut prison in the older Haliburton range. The chamber is an architectural survival, but the evidence does not justify assigning every person accused or punished in the area to that specific space.
When Deborah and I visited on June 15, 2026, after touring Tantallon Castle, Dirleton’s contrast was striking. Gardens and lawns surround a ruin that contains both refined domestic spaces and a severe prison cut into bedrock. That tension makes the site memorable: hospitality, household life, defense, and punishment existed within the same complex.

Our full Dirleton Castle history and visitor guide explores the gardens, family occupation, architecture, and practical details in greater depth. For the dungeon traveler, Dirleton is most valuable as a reminder that a prison can survive physically even when the identities and experiences of many captives remain uncertain.
Rothesay Castle
Rothesay Castle on the Isle of Bute offers one of the most direct dungeon experiences among these sites. Its dungeon is reached today by descending a metal ladder, a route that emphasizes the separation between the chamber and the occupied castle above.
The circular castle also connects the western seaways with royal and regional power. Visitors should judge the descent according to their mobility and comfort in confined spaces. Even without entering, the access arrangement helps explain how dependence on a guard could become part of punishment.

Planning a Scottish Castle Dungeon Journey
Opening arrangements, boat sailings, weather closures, and interior access can change. Check each castle’s current official information before traveling, especially for Lochleven Castle, where the boat depends on conditions and water levels.
Wear footwear suited to wet stone and uneven surfaces. Expect narrow stairs, low openings, ladders, and limited light. At Blackness and Lochleven, the landscape is part of the interpretation, so allow time for the courtyard, shoreline, island, and views rather than concentrating only on the chamber labeled as a dungeon.

What These Prisons Reveal
Scottish castle dungeons were not one standardized room type. They ranged from pits and rock-cut chambers to tower rooms, military vaults, and guarded residential quarters. The seven castles show that confinement was shaped by rank, politics, architecture, and geography.
Walking through these spaces also changes the scale of history. A royal abdication, religious conflict, war, or political protest becomes connected to a stair, a barred opening, a window seat, or a boat landing. For heritage travelers and family historians, that physical context is often the most lasting part of a visit.
