The story that haunts this land
Your quest begins at the House of Mr. Sax, transformed into a museum since 2014, where Adolphe Sax was born in 1814. Here, you examine reproductions of original instruments designed by Sax in the 1840s, searching for the first clues of this conspiracy. Rue Adolphe Sax, a 300-meter paved pedestrian street, then leads you towards the Collegiate Church of Notre-Dame, lined with wind instrument shops, testifying to the old artisanal street of the 19th century, a center for instrument making in Dinant and its Walloon heritage.
Continuing your investigation, you reach the Collegiate Church of Notre-Dame de Dinant, a Gothic church built between 1530 and 1697. Its 68-meter-high bell tower, adorned with 42 bells, the heaviest weighing 11 tons, dominates the city. The interior reveals 1700 blue and white sgraffito motifs, dating from 1530 to 1540, offering a magnificent setting for your search for hidden messages. The Charles de Gaulle Bridge, rebuilt in 1978 after its destruction in 1914 and 1940, allows you to cross the Meuse, a symbolic crossing towards Dinant's secrets.
Walking along the Quai des Croisières, you head towards Place Victor Collard. Here stands the Statue of Adolphe Sax, erected in 1952. This 3-meter-high bronze work by sculptor Égide Melin was inaugurated for the centenary of the saxophone's invention, and depicts Sax presenting his instrument patented in 1846. The symbolism of this statue is crucial to understanding the inventor's legacy and the importance of his work for Wallonia's musical heritage.
Your journey then takes you to the Rocher Bayard, a natural site in Dinant. This 40-meter-high limestone rock, split by legend in the 8th century, with a fissure only 1.5 meters wide, was formed by natural erosion over 10,000 years. The legend of the horse Bayard carrying the four Aymon sons in a single leap across the Meuse, though distinct from Sax's story, reminds you of nature's and myth's capacity to shape landscapes and narratives. This place offers a moment of reflection before you approach the conspiracy's resolution.
The Citadel of Dinant, a military fortress rebuilt between 1821 and 1827, overlooks the Meuse at a height of 100 meters. After climbing the 100 steps from the bridge, you explore the 14-18 war museum, which houses 25,000 objects and two 120-meter galleries. It is in this place, steeped in history, that you assemble the last pieces of the puzzle, revealing the truth about Adolphe Sax's legacy and ensuring that his genius, a major contribution to Walloon heritage, will never be forgotten. Your visit to Dinant concludes with the restoration of the inventor's memory, a true GPS treasure hunt in the heart of history.
