Just above the low wall on your right, you can spot the top of an old stone tower. Keep walking uphill and step back a little, and you’ll see it more clearly. This isn’t just any tower—it’s the oldest surviving piece of Liège’s medieval walls, built more than a thousand years ago during the time of Notger, the very first prince-bishop. In other words, it’s a rare witness to the birth of the principality of Liège around the year 1000. Its position on the Publémont hill was strategic, guarding the city between two fortified gates that have long since disappeared or been transformed. But the tower’s story is anything but peaceful. In 1468, it was destroyed during the brutal sack of Liège by Charles the Bold, then rebuilt in 1483. To mark the event, an inscription was carved into its facade, a verse so hard to decipher that locals nicknamed it “the Devil’s Stone.” Over the centuries the tower underwent several restorations, including a dramatic rescue in the twentieth century when a determined owner dug out more than 250 tons of earth that had filled it up. Today, it’s closed to visitors as it stands on private property, but you can still catch a glimpse from the Thier de la Fontaine. Even its name has a story: “Moxhons” comes from the Walloon word for “sparrows”—maybe because birds once nested there, or perhaps because the tower seemed small compared to the city’s massive fortifications. Whatever the reason, the Tour aux Moxhons remains like a book in stone, bearing witness to both the resilience and the rebirth of the fiery city.
