Ghana’s coastal slave castles | Sophie's World Travel Inspiration

I did not expect silence to be the loudest thing I encountered in Ghana.

This country welcomes you with warmth: sun on your shoulders, waves crashing playfully against the shore, salt in the air, music spilling from passing cars, laughter and life.

And then, a stillness that demands attention. At the coastal forts and castles, Ghana quietly asks you to remember. Stepping into Fort Prinzenstein, or Christiansborg Castle, you’re not just sightseeing. This is an emotional journey through layers of history that still shape the present.

Standing here, knowing what happened and how many lives were changed forever, is uncomfortable in a way that sticks with you… visiting these sites are less about travel and more about remembering.

Fort Prinzenstein: A lonely witness by the sea

Fort Prinzenstein is at the edge of the Atlantic Ocean in Keta.

If you don’t know what you are looking for, you can easily miss it.

Today, the ocean presses up against the walls, slowly wearing the place down. Parts of it are already gone. It feels like time itself is slowly reclaiming the crumbling structure. What about the stories inside here? Will they be forgotten, too?

It is modest in size, Fort Prinzenstein – but immense in meaning. Learning that this hub of the transatlantic slave trade was built by the Danes in 1784, when my own country was still a part, however unwilling, of then Denmark-Norway, makes me queasy.

Walking through the fort, the silence is striking. This intimate, fragile space somehow makes the brutal history hit harder.

The rooms are narrow and dark, with low ceilings that force you to bow your head as you move through them. It is impossible to not think about the physical and emotional weight carried by those who were confined here – waiting, before being forced onto ships, not knowing where they would be taken, or if they would survive the journey ahead.

I stop in one of the smaller rooms, and the air feels thick even though the doorway is open. The heat lingers, and breathing feels harder than it should. I can’t help but think about the many people crammed in there. The smell of sweat. And fear.

What strikes me most, is how exposed the fort is. Unlike larger coastal forts with imposing walls, Prinzenstein feels vulnerable, both to the elements and to memory.

The ocean

The ocean is right there – beautiful, endless, almost cruelly indifferent. I can hear the waves breaking rhythmically against the shore. It’s a steady, almost soothing sound.

The contrast is unsettling. Standing on the shore, I am very aware that this same sound once marked the final moments of familiarity, the last glimpse of home they would ever see.

There is no spectacle here, no attempt to soften the experience. Fort Prinzenstein does not overwhelm you with displays or explanations.

Instead, it invites stillness. It asks you to pause, to imagine, to mourn. In that quiet, I feel a heaviness. A mix of anger, grief, responsibility even, and deep respect for those resilient souls that passed through.

Places like this are not meant to be comfortable. They are meant to be remembered, even as the sea slowly threatens to erase them.

Christiansborg Castle (Osu Castle): Power, politics, and pain

On the coast in Accra, Christiansborg Castle (also known as Osu Castle) has a more complicated history. It has passed through many hands: Danish, Portuguese, British. And later, after Ghana’s independence, it became HQ of the new government.

Visiting Christiansborg is a very different experience from Fort Prinzenstein. This castle is immediately imposing. At first glance, the whitewashed walls and sweeping views of the ocean seem almost serene. But as you move through the dungeons and holding cells, that calm dissolves. Slave traders designed these spaces for control: thick walls, minimal light, and a heavy sense of power.

One detail that stays with me is learning that Queen Elizabeth II visited Ghana and stayed at Christiansborg for 11 days during her historic post-independence tour in 1961.

The image is striking: a queen sleeping within these walls, dining in candlelit halls, whilst directly beneath her feet were the dungeons where enslaved people once were imprisoned. Upstairs, royal banquets and formal receptions. Downstairs, rooms where enslaved Africans waited in darkness. Two completely different stories sitting side by side, staring you right in the face.

The return

I walk down a narrow spiral staircase, and through a Door of No Return. My steps slow as the air shifts – warm above, cool and damp below. My legs feel heavy, my breath deliberate. I try to imagine how this must have felt centuries ago, with no hope and no idea where you were going.

Even more compelling is the path upward. At Christiansborg, people not only left through the Door of No Return – they also came back through it. Returned, freed individuals walked back into this castle, retracing their steps. Climbing up the same staircase from the dungeons into the light feels symbolic. Like reversing history. And reclaiming a space that was once used to dehumanise.

What makes Christiansborg striking is its complex history. You can feel the echoes of suffering from the slave trade, but the same walls also held colonial rulers, and later, the leaders of an independent nation. Again, the contrast is jarring – rooms where enslaved Africans were once held prisoner, near offices where centuries later, political decisions were made. I’m reminded how power and oppression often have been closely intertwined.

Thoughts on Ghana’s coastal forts and castles

Visiting Ghana’s coastal forts and castles is not easy, nor should it be. These places are reminders of resilience as much as they are of cruelty. They ask Ghanaians, members of the African diaspora, travellers from around the world – all of us – to pause, reflect, and acknowledge a shared history.

The contrast between modern-day Ghana and the painful stories embedded in these walls are poignant. If you are in Ghana, make time for these two sites. And go with respect and curiosity. Go ready to listen. Between the stone walls and the restless sea are stories that deserve to be remembered. Not only as distant history, but as part of our collective human journey.

Long after leaving Ghana, it is the sea I remember most. The same waters that once carried bodies away, now receive people who return. It’s as if I can see them here at the shoreline, breathing deeply, taking their space back.

Constant, shimmering, and seemingly unchanged, it has witnessed centuries of departure and return, this ocean. Waves that once carried ships filled with suffering, now lap against a coastline, very much alive with music, life, and energy.

And standing at the water’s edge here, I’m reminded that memory, just like the sea, doesn’t go away. Restless, reflective, and impossible to ignore. The sea remembers what the world tries to forget. It has carried grief, stolen futures, and names that were never spoken, all across generations.

The ocean does not erase what happened, it holds it. So when the waves meet the shore, they are not just arriving – they are remembering.
