Montjuïc Castle

Sea wind moves across old stone walls. Gulls hang in the air above a wide, grassy moat. From up here the port of Barcelona spreads out below: cranes, containers, ferries, and the open Mediterranean beyond. This is Montjuïc Castle, the fortress that watched over the city for nearly four centuries.

The hill of Montjuïc rises about 170 meters almost straight from the sea. Its name probably means Jewish mountain in old Catalan, and a medieval Jewish cemetery lay on these slopes. Long before any fortress, a simple watchtower stood on this spot. Guards lit signals when strange sails appeared on the horizon. The place was born for watching.

The first real fort went up in a hurry, in 1640. Catalonia had risen against the Spanish crown in the conflict known as the Reapers' War, and France had entered the fight on Catalonia's side. In January 1641 a royal army marched on Barcelona. Catalan and French troops met it on these slopes and pushed it back. The Battle of Montjuïc saved the city, at least for a time.

The fortress you walk through today mostly dates from the eighteenth century. After 1751 the military engineer Juan Martín Cermeño rebuilt it as a modern star fort. Walls meet at sharp angles, so cannons could sweep every approach. Barracks, a parade ground, and vaulted storerooms filled the interior. A wide dry moat circled the whole structure. For its era, this was state of the art.

Montjuïc played a strange double role. Its guns faced the sea, but they could also turn toward the streets below. More than once, the castle threatened the city it was meant to protect. In 1842, during an uprising, government forces bombarded Barcelona from this hill. Hundreds of buildings were hit. The message was clear: the fortress ruled the city, not the other way around.

For long periods the castle served as a military prison, and its name grew dark. In the 1890s, after bomb attacks in the city, hundreds of anarchists and union workers were held and tortured here. Reports from the Montjuïc trials shocked readers across Europe. In 1909 the educator Francesc Ferrer i Guàrdia was executed on this hill after a week of riots in the city. Many historians judge his trial unjust.

The heaviest date came in 1940. On 15 October, a firing squad of the Franco regime executed Lluís Companys, the president of Catalonia. German police had arrested him in occupied France and handed him over. He died in the moat known as Santa Eulàlia. It is said that he refused a blindfold and asked to stand barefoot, to feel the soil of his country.

A memorial near that spot honors him today. Fresh flowers appear there through the year. For many people in Catalonia, this quiet corner is the most important place on the whole hill. Take a moment there. Silence is a fair response.

The army held the castle long after the fighting ended. For years it housed a military museum. In 2007 the state finally handed the fortress to the city of Barcelona. Today its rooms hold exhibitions that explain this layered past, including the painful chapters.

Now walk the ramparts. The star-shaped bastions push out at each corner, and old cannons still point at nothing. On the seaward side you look straight down into the working port: container ships, stacked steel boxes, slow cranes. Airplanes sink toward the airport south of the harbor. On the landward side the whole city unrolls, and from the highest walls you can spot the towers of the Sagrada Família.

Around the walls, the old moat has become a garden. Lawns and hedges fill spaces where soldiers once drilled. Families picnic under the walls, and runners circle the paths in the evening. In summer, an open-air cinema fills the moat with screens and deck chairs. The contrast is strange and healing at the same time.

Getting up is easy. A cable car, the Telefèric de Montjuïc, lifts you from the funicular station to the castle gate in a few minutes. Bus 150 also reaches the entrance. Walking down takes about half an hour through pines and gardens. Summer sun is strong on the bare hilltop, so carry water.

Before you leave, rest your hand on the warm stone of the parapet. This fortress bombarded its own city, held its prisoners, and shot a president. Now visitors photograph sunsets from its walls. The hill still watches the sea. What it guards today is memory.
