The story that haunts this land
Your journey begins at Place Saint-Lambert, once the site of the ancient Carolingian cathedral founded around 717 by Saint Lambert. This vast 10,000 m² esplanade was the administrative center of Liège, hosting markets and gatherings since the 13th century. The Palace of the Prince-Bishops, built between 1037 and 1049 under Bishop Notger, stands proudly with its Baroque facade remodelled in the 18th century. It was the residence of the prince-bishops until the Liège Revolution of 1790 and now houses the palace of justice, testifying to the privileges granted to the armourers' guilds in the 14th century.
Continue your investigation by crossing the Passage Lemonnier, an Art Nouveau gem built in 1903 by Joseph Lemaire. This 50-meter-long covered passage connects Rue Léopold to Boulevard de la Sauvenière, its decorative stained glass and ironwork illustrating the Liège 1900 style. Next, the Place du Marché reveals the Perron of Liège, a symbolic column erected in 1697. Standing 19 meters high, it embodies the communal liberties regained in 1312 and the city's power against princely authority since the Battle of Othée in 1408, a monument classified as Wallonia's monumental heritage since 1952.
Your route then takes you to the Collegiate Church of Saint-Barthélemy, a Romanesque church founded around 1020, whose nave was erected between 1060 and 1180. There you will discover the 11th-century octagonal baptistery, one of the oldest in Western Europe with its 6.5-meter diameter. This is where Renier de Huy's bronze baptismal font, made around 1107-1118, a Mosan masterpiece, reveals the prowess of Liège artisans and their connection to metalwork, essential for armour making.
The path then leads you to the Quai de la Batte, then to the Pont des Arches, a masonry bridge over the Meuse built between 1862 and 1869, 400 meters long with 13 arches. It replaces an old medieval bridge from the 13th century and has been classified as Wallonia's heritage since 2009. This strategic site was a vital crossing point for goods and people, including armourers and their productions. The city of Liège, with its Art Nouveau network and monuments, unfolds at every step.
Your quest concludes on the Montagne de Bueren, a monumental staircase of 374 steps, built in 1881. With a total height of 112 meters, it connects the city center to the citadel, paying homage to Pierre de Bueren, hero of the defense against Charles the Bold in 1468. By climbing its steps, you will have deciphered the secrets of Liège's armourers, understood the history of the Fiery City and its exceptional heritage. This thematic circuit in Wallonia will have offered you a unique interactive visit, combining history, architecture and discovery of Walloon monuments.
