In the very heart of Ghent, at the confluence of the arms of the River Lys, rises the formidable silhouette of Gravensteen. It is the only medieval fortress in Flanders whose defensive system remains virtually intact to this day. Massive stone walls, 24 defensive turrets, a deep moat, and a towering keep create the impression of an impregnable stronghold that has stood as one of Ghent`s main symbols for over eight centuries.
Gravensteen is open to visitors year-round and offers a unique opportunity to immerse yourself in the medieval atmosphere: walk along the fortress walls, climb to the viewing platform, see a collection of ancient weaponry, and even venture into the grim dungeons where prisoners were once tortured.
History of Gravensteen
Early Fortifications (9th–11th Centuries)
The history of Gravensteen began in the 9th century when Count Baldwin I Iron Arm built the first wooden fortification here to defend against Viking raids. In the 10th century, Count Arnulf I significantly rebuilt the fortress, creating a fortified encampment with wooden structures around a central building on an artificial hill.
Under Count Robert I the Frisian (11th century), a three-story stone tower appeared on the site of the wooden structures, featuring grand halls, a monumental staircase, fireplaces, and even latrines – at the time, this was considered a sign of unprecedented luxury.
Gravensteen`s Modern Form (1180)
The fortress acquired its present appearance in 1180 under Count Philip of Alsace, who had participated in the Second Crusade. Inspired by the crusader castles he had seen in the East, Philip erected a powerful stone citadel on the site of the wooden castle that had burned down in 1176.
Gravensteen was conceived not only as a defensive structure but also as a symbol of the power of the Counts of Flanders. It was meant to serve as a counterweight to the wealthy houses of the nobility built on the opposite bank of the River Lys and to demonstrate to the townspeople who the true master was.
From 1180 to 1353, Gravensteen served as the residence of the Counts of Flanders.
Decline and Change of Function
In the 14th century, Count Louis II of Male found the castle insufficiently comfortable for living and moved his residence to a more pleasant palace complex. However, Gravensteen did not become empty – it retained its administrative significance.
From 1353, the Ghent Mint was housed here. From 1407, Gravensteen became the meeting place of the Council of Flanders – the highest judicial body of the county – and served as a prison. For four centuries, justice was dispensed here, often harsh and relentless.
In the 18th century, a period of neglect began. In 1778, the Council of Flanders left the castle walls, and the structure was sold off piece by piece to private owners. In 1807, during the Industrial Revolution, the main tower was converted into a textile factory, and workers with their families settled in the other buildings. Gravensteen fell into a deplorable state and was nearly ready for demolition.
Revival: Restoration in the 19th–20th Centuries
In the late 19th century, city authorities and the local nobility recognized the historical value of Gravensteen. In 1885, the city of Ghent began gradually purchasing the castle back from private hands. Between 1893 and 1907, a large-scale restoration was carried out under the direction of architect Joseph de Waele. De Waele sought to restore Gravensteen to its presumed 12th-century appearance, and although some details do not fully correspond to historical accuracy, the result is impressive.
The restored castle became the centerpiece of the 1913 World`s Fair and has since become one of Belgium`s main tourist attractions. In 1980, on the occasion of Gravensteen`s 800th anniversary, a new phase of restoration and structural reinforcement began, ensuring the preservation of this unique monument for future generations.
What to See Today at Gravensteen
Exterior and Architecture
Gravensteen is a powerful fortification built on an artificial hill, surrounded by a moat that was once fed by the River Lys. The central feature is the keep – the main tower, about 30 meters high, which housed the count`s residential quarters. Around the keep are the residential wings, stables, and other ancillary buildings.
The fortress is encircled by an oval defensive wall topped with 24 small turrets called échauguettes, which overhang the moat and were used for all-around defense. The entrance to Gravensteen is through massive gates with a drawbridge.
Interior Spaces
The Great Hall – the ceremonial hall of Gravensteen, where feasts and receptions were once held. Here you can imagine the splendor and grandeur of the court of the Counts of Flanders.
Museum of Justice and Weaponry – Gravensteen houses a permanent exhibition dedicated to the history of justice in Flanders. The centerpiece is a collection of medieval torture instruments – a grim reminder of how justice was administered in those times. On display are the rack, the Spanish boot, the "iron maiden," and other devices that evoke a mix of horror and curiosity in visitors. Adjacent to the torture exhibit is a rich collection of historical weapons and armor, assembled in the 19th century. Here you can see knightly swords, spears, crossbows, full suits of armor, and helmets from various eras.
The Dungeons – the dark basement rooms of Gravensteen served as places of imprisonment for prisoners awaiting trial or execution. Here you can sense the harsh conditions in which the captives were held.
Fortress Walls and Viewing Platform – one of the main pleasures for visitors is a walk along the fortress walls and the climb to the keep`s viewing platform. From here, a breathtaking panorama of medieval Ghent unfolds: the winding canals, the spires of Saint Bavo`s Cathedral, the Belfry, and Saint Nicholas` Church. This is the best spot in the city for photographing the historic center.
Walking along the outer wall requires caution – next to the narrow pathway, there is a sheer drop of several meters. Be careful, especially if you have children.
