Blackness Castle

Listen first. Waves slap against black rock, a few steps below the walls. The wind comes straight off the water, cold and salty, and it pushes against you as you walk. Underfoot, the stones are uneven and worn smooth. Gulls call overhead. Across the wide grey river, low hills fade into haze. This is Blackness Castle, a fortress that sits so close to the sea that the tide nearly touches its walls.

The water in front of you is the Firth of Forth. A firth is a Scottish word for a long sea inlet, where a river meets the open sea. The castle stands on a narrow spit of rock on the southern shore. The royal town of Linlithgow lies a few miles inland. For centuries, this little harbour was Linlithgow's port. Goods came in here by ship and went up the road to the town and its royal palace.

The castle began in the fifteenth century. It was built by Sir George Crichton, one of the most powerful men in Scotland in his day. His family was deeply involved in the dangerous politics around the young Stewart kings. A strong house on the water gave him a secure base, control of the harbour, and a view of every ship that passed. Within a generation, the castle had passed to the Crown. From then on, it served the kings and queens of Scotland.

Now look at the overall shape of the building. Locals have long called it the ship that never sailed. The long, narrow walls follow the line of the rock, and they taper to a point at the northern end, out over the water. That pointed end is the bow. The tall south tower is the stern. And the central tower rises in the middle like a main mast. Once you see the ship, it is very hard to stop seeing it.

Here is something many visitors miss. Blackness was not mainly a home for nobles, and it was not mainly a defence against invaders. For much of its life, it was a state prison. The Crown sent important and inconvenient people here. They were close enough to watch from the royal palace at Linlithgow, but far enough away to keep out of trouble. Political rivals, churchmen, and nobles out of favour all spent time behind these walls.

One of the best-known prisoners was Cardinal David Beaton, a senior churchman in the turbulent years of the sixteenth century. He was held here for a time after the death of King James the Fifth, during a fierce struggle for power. In the following century, the castle held Covenanters. They were Presbyterians who refused to accept the king's control over their church. For them, this rock in the river was a cold and lonely place.

The central tower held the most important prisoners, and conditions there could be fairly comfortable. The lowest prisoners had a far worse fate. At the base of the north tower, there is a pit prison. It is a dark space reached only from above. According to traditional accounts, the tide could seep in through the rock, so prisoners sat in cold sea water. It is a grim thought to carry with you as you walk towards the bow.

In the sixteenth century, warfare changed. Cannon could smash medieval walls, so castles had to adapt. At Blackness, the defences were rebuilt and made much thicker, especially on the landward side, facing the approach you walked along. The works are linked to Sir James Hamilton of Finnart, a skilled royal builder of the time. Look at the massive south wall and the gun holes cut into the stone. They were designed for cannon, not bows.

Those thick walls were tested in the middle of the seventeenth century. Oliver Cromwell's army invaded Scotland, and Blackness came under attack from both land and sea. The castle was battered and eventually surrendered. Afterwards, it was repaired, and it continued to serve as a garrison fortress and prison. Walk along the walls and look closely. The stonework shows different phases of building and repair, layered one over another, like a record of the castle's hard years.

The story does not end with kings and cannon. In the later nineteenth century, the army turned Blackness into an ammunition depot. Gunpowder and shells were stored here, safely away from towns, with easy access by water. That is why there is a long pier running out into the Firth. It allowed boats to load and unload supplies. This military use continued into the early twentieth century, and only then did the castle begin its new life as a historic monument.

Today, the castle is looked after by Historic Environment Scotland. It has also found a second career on screen. Film and television crews like its raw, unchanged look. It appeared in a 1990 film of Hamlet, and more recently it played an eighteenth-century army fort in the television series Outlander. Fans sometimes arrive expecting a film set. Instead they find real stone, real wind, and real sea, which is far more interesting.

If you can, climb up into the central tower and onto the walkways. From the higher levels, you look straight along the ship-shaped walls towards the point. Out in the Firth, you can see the long red bridges that cross the water further upstream, near Queensferry. Ships still pass along the river. Standing here, it is easy to understand why a lord, and then a king, wanted to hold this exact spot.

Before you leave, walk out along the pier, or stand on the shore just outside the gate. Turn and look back. From here, the castle looks low and long, with the water at its feet. The grey walls almost match the colour of the rocks and the sky. Listen again to the waves on the stone. The prisoners, soldiers and gunners heard that same sound. It is still here, long after the ship that never sailed went quiet.
