Alcazaba of Almería

Start with your feet. The path climbs in gentle zigzags, and the ground underneath is old stone and packed earth, warm even in the shade. A breeze comes up from the harbour below and carries a faint smell of salt. Somewhere ahead you hear water running through narrow channels. Look up, and the walls stretch along the ridge, the colour of sand and dry honey against a hard blue sky. This is the Alcazaba of Almería. For about a thousand years, this fortress has watched over the city and the sea.

The word alcazaba comes from Arabic. It means a citadel, a fortified enclosure on high ground. In the tenth century, this part of Spain was ruled from Córdoba. The Caliph Abd al-Rahman the Third, the most powerful Muslim ruler in western Europe at the time, gave Almería the status of a city. The fortress grew from that decision. Its job was clear: to protect a port that was becoming one of the busiest in the western Mediterranean.

The city's old Arabic name was al-Mariyya. People translate it in different ways. Some say it means the watchtower. Others prefer a more poetic reading, something like the mirror of the sea. Nobody can settle the question for certain. But stand at any opening in these walls, and both versions make sense. You can see far out over the water, and on a still morning the bay shines like polished metal.

The fortress is not one building. It is a chain of three walled enclosures, one after another along the hilltop. Each enclosure belongs to a different chapter of the story. As you walk upward, you move forward through time. The first two enclosures come from the Islamic centuries. The third, at the very top, is Christian. So this short walk takes you from the age of the caliphs to the age of Ferdinand and Isabella.

The first enclosure is the most open. Today it is full of gardens, terraces, and those water channels you heard at the entrance. Water was precious in this dry corner of Andalusia, and Islamic builders treated it with great care. They moved it quietly, in thin streams, from basin to basin. The gardens you see now are a modern reconstruction, but they follow that old idea. In times of danger, this wide space also gave shelter to people from the town below.

Look to the side, toward the next hill. A long wall runs down into the valley and climbs again up the far slope. That wall connected the fortress to the hill of San Cristóbal. It belongs to the eleventh century, when the caliphate had broken apart. Spain then split into small rival kingdoms called taifas. Almería became the capital of one of them, and its rulers strengthened the defences. On top of that far hill stands a white statue of Christ, added much later.

Now comes the second enclosure... and the mood changes. This was the heart of power. Here stood the palace of the taifa kings, with courtyards, halls, baths, and houses for the people who served the court. One ruler, al-Mutasim, is remembered as a patron of poets, and his court had a reputation for refinement. Today you mostly see foundations and low walls. Archaeologists have uncovered the outlines of rooms and streets, so you can trace the plan with your eyes.

Here is something many visitors walk straight past. Inside this enclosure there is a small chapel. It stands on the site of an earlier mosque. After the Christian conquest, the new rulers turned the prayer space into a place of Christian worship. Look closely, and you can still find traces of the Islamic building inside it. One small structure carries both faiths in its stones.

In December 1489, Almería surrendered to the Catholic Monarchs, Ferdinand and Isabella. This was only a few years before the fall of Granada, the last Muslim kingdom in Spain. The new rulers did not destroy the fortress. They took it over and changed it. They wanted a castle built for a new kind of war — a war with cannons. Medieval walls were tall and thin. Gunpowder needed something thicker and lower.

That is the third enclosure, at the top of the hill. Its walls are heavier, and the style is clearly different from the earlier parts. There is a strong keep, a parade ground for soldiers, and rounded towers designed to resist artillery. Notice how the stone changes as you cross into this area. It feels squarer and more military, with less decoration. You are looking at the end of the Middle Ages and the start of a new era of fortification.

The fortress also had to survive nature. In the sixteenth century, a strong earthquake struck Almería and badly damaged the city and these walls. Over the following centuries, the citadel slowly lost its military purpose and fell into decline. Much of what you see today is the result of careful restoration in the twentieth century. So the walls show many layers of building, repair, and rebuilding, one on top of another.

Here is a second surprise. In recent years, these walls have appeared on screens around the world. Film and television crews have used the fortress as a location, including for the series Game of Thrones. It makes sense. The surrounding landscape of Almería is one of the driest in Europe, and filmmakers have come to this region for decades. With its golden stone and desert light, the Alcazaba easily becomes an imaginary city from another world.

Before you leave, find a quiet spot along the walls and look down. Below you, the houses of the old neighbourhood of La Chanca spread across the slope, many of them painted in bright colours. Beyond them lie the port, the cranes, and the open sea. Listen for a moment. Traffic, a dog barking, gulls over the harbour. The guards who stood here a thousand years ago watched this same water. As you walk back down, feel the path under your feet once more, and notice how the city slowly rises up to meet you.
