« May the sound of the trumpet depart »— Official motto of the city of Namur
Your investigation begins on Place Saint-Aubain, facing Saint-Aubain Cathedral. This classical baroque edifice, built between 1751 and 1775 by Gaetano Piola, is dedicated to Saint Aubain, Bishop of Tongres in the 5th century. The square, a historical starting point for religious processions, is surrounded by listed 18th-century buildings. It is here, in the shadow of the Episcopal Seminary founded in 1602, that Marie Toussaint was reportedly last seen before her arrest, her gaze perhaps crossing the polychrome marbles and the 45m high dome of the Cathedral, listed as Walloon heritage since 1949. The Episcopal Treasury of Namur, housing over 1000 liturgical objects from the 13th to 20th centuries, might contain forgotten parchments.
Proceed to the Old Palace of Justice, a neoclassical building erected between 1818 and 1823 on the remains of the old 17th-century prison. This site, 300m from Place d'Armes, served as the seat of the revolutionary tribunal under French rule from 1795 to 1814. Although the current edifice post-dates Marie Toussaint's era, its location is steeped in a judicial history that traces back to her trial. The 50m long facade, adorned with Doric columns and listed in 1952, has witnessed the evolution of Namur's judicial system, from witch hunts to more modern judgments. Here, you will search for traces of procedures, decrees from the period that might have sealed her fate.
Place d'Armes, the heart of Namur's historic district since the 13th century, is your next stop. Formerly the site of the comital castle razed in 1215, it was the scene of medieval public executions, 500m from Saint-Aubain. It is here, facing the statue of King Albert I erected in 1930, that the people of Namur gathered to witness judgments and condemnations. The 17th-18th century mansions surrounding it have seen centuries of popular justice. You will look for the marks of executioners, echoes of cries, and testimonies of chroniclers of the time, who may have recounted Marie Toussaint's tragic end.
400m from Place Saint-Aubain, via the cobbled Rue Saint-Loup, stands the Saint-Loup Church. This baroque Jesuit church, built between 1621 and 1646 and restored after the Siege of Namur in 1692, is famous for its 12 17th-century carved wooden confessionals and illusionistic frescoes. Listed as a historical monument in 1936, it was a central place of the Counter-Reformation in Namur. The Jesuits, fervent defenders of religious orthodoxy, may have influenced the judgments of the time. You will explore the confessionals, searching for secret confessions or hidden clues that could shed light on the truth behind the accusations against Marie Toussaint. The Pont de France, Europe's second-longest suspension bridge upon its inauguration in 1866, will offer you a view of the Meuse-Sambre confluence, a vanishing point towards other horizons for the condemned.
Your journey concludes with a view of the Belfry of Namur, a UNESCO listed belfry in 1999, rebuilt between 1818 and 1821 after its destruction in 1794. Standing 75m high with its carillon of 46 bells, it has been a symbol of communal liberties since 1346 and offers a 360° panorama after 378 steps. Although post-dating Marie Toussaint's trial, the belfry, 600m via Place d'Armes, embodies the voice of the city and its citizens, many of whom may have been witnesses or actors in her fate. By traversing these sites in Namur, you are not just following an itinerary: you are tracing the twists and turns of an era of superstition and power, disentangling facts from legends, and giving a voice to the forgotten history of Marie Toussaint. This exploration of Wallonia's heritage immerses you in the city's judicial and religious past, revealing the layers of history that have shaped the Walloon capital.
