Your quest begins in front of Bouillon Castle, a Belgian historic monument built in the 10th century to control the Semois valley. This is where Godfrey of Bouillon, Duke of Lower Lorraine, reigned from 1075 before selling his possessions in 1096 to finance the First Crusade. Explore its 2 hectares and 5 visitable floors, where the 11th-century guardroom and drawbridge echo with the knights and strategists who forged Bouillon's history. This site is key to understanding Godfrey's departure and the secrets he may have left behind.
The route then leads you to the Pont de Cordemois, an 18th-century stone bridge spanning the Semois, connecting the city center to Bouillon's historic district. This bridge, restored in 2005 for pedestrian safety, was a strategic medieval point for trade and defense of the castle. Its approximate length of 100 meters made it an essential passage, even in the time of Godfrey I of Bouillon, for the exchanges that animated the city and troop movements. It testifies to the importance of the Semois in Bouillon's development.
Continue towards the Church of Saint-Pierre and Saint-Paul, a parish church built in 1771 in the Walloon Baroque style. Its 35-meter bell tower houses a bell from 1623, a remnant of an earlier era. This place of worship, connected to the Bouillon community since the 17th century, with its altars classified in 1954, reveals the spiritual evolution of the town. The frescoes and stained glass windows might hide symbols that only a keen eye, like that of a scholar from the Duchy of Bouillon, could decipher for your quest for the legacy.
Place Ducale, Bouillon's historic heart, is your next stop. Surrounded by 17th and 18th-century houses, this square was the site of medieval markets under Godfrey of Bouillon in the 11th century. Paved with local stone and adorned with a 19th-century fountain, it is the center of the pedestrian district, less than 500m from the castle. This is where news spread, oaths were exchanged, and merchants conducted their business. The Remparts de Bouillon, medieval vestiges from the 12th century, surround you, protecting the upper town for about 1 km. Restored in the 19th century under Leopold I, they incorporate 4 fortified gates and recall Bouillon's defensive power.
Approaching the Maison du Bailli, a 17th-century house classified in 1980, you discover the former residence of the bailiff of the Duchy of Bouillon, a witness to the post-Godfrey administration. Its gabled stone facade and 16th-century vaulted cellar tell another facet of Bouillon's history. Your journey concludes in front of the Statue of Godfrey of Bouillon, erected in 1904 by the city. This 4-meter bronze work commemorates the 800th anniversary of the capture of Jerusalem in 1099, sealing the imprint of this leader of the First Crusade. This outdoor escape game will have allowed you to grasp the essence of Bouillon, from its 11th-century castle to its narrow streets, a true thematic circuit at the heart of Walloon heritage.
