The story that haunts this land

Your quest begins on the Grand-Place of Mons, the administrative and commercial heart of the city since the Middle Ages. Surrounded by Flemish and classical facades, rebuilt after the destructions of 1940-1945, this square is the nerve center of any exploration of Mons' heritage. It is here that Hainaut's urban autonomy was affirmed, a history you will decipher by exploring every corner. The stories of merchants and magistrates still resonate, inviting you to an interactive tour of Mons' soul.

Continue towards the Maison de la Mémoire de Mons, an interpretation center that documents local history and 20th-century events. Located in the city center, this site for transmitting Mons' collective memory offers insight into the city's challenges and renaissances. Not far, the Collegiate Church of Sainte-Waudru of Mons, a major edifice of Hainaut's religious heritage, whose construction began in 1450 and gradually completed until the 17th century, reveals its flamboyant Gothic style. It houses the reliquary of Sainte-Waudru (Waltrude), founder of the Mons monastery in the 7th century.

Your journey then leads you to the Belfry of Mons, inscribed on the UNESCO World Heritage list in 1999 as one of the 56 belfries of Belgium and France. Dominating the Grand-Place of Mons, this 87-meter tower is a symbol of urban freedom. Its initial construction dates back to the 12th century (around 1150), with a major reconstruction in the 15th century after several fires. Its carillon of 49 bells, the oldest dating from 1657, will remind you of the fortified city's constant vigilance. It is a central point for understanding the history of Mons.

Explore Square Saint-Germain of Mons, a historic public space redeveloped in the 19th century, near the old ramparts and medieval fortifications. These vestiges, integrated into the current urban landscape, bear witness to the strength of "Mons Fortis." The path then leads you to the British Memorial of Mons, which commemorates the Battle of Mons on August 23, 1914, the first major engagement of British troops in Belgium during World War I. This site recalls the British military presence and Allied losses in the collective memory of Hainaut.

Conclude your exploration at the Jardin du Mayeur of Mons, a historic green space developed in the 19th century, named after the function of Mayeur (mayor) of Mons. This place for walking and relaxation, integrated into the urban fabric of the historic center, offers a serene perspective on the city's evolution. By revisiting the historic ramparts and fortifications of Mons, you will understand how this fortified city of the Middle Ages, with its successive enclosures dismantled in the 19th century, managed to preserve traces of its past. Your interactive visit to Mons will have offered you a unique perspective on Belgium's world heritage.
