Citadel of Namur

Massive fortress on the rocky spur above the Sambre and Meuse, with ramparts, tunnels, and panoramic views

The Citadel of Namur towers over the confluence of the Sambre and Meuse on a great rocky spur. There has been a fort here since the Middle Ages, and the present complex — much of it the work of seventeenth-century Dutch, Spanish and French engineers — is one of the largest fortified sites in Europe.

You can walk the ramparts and the wooded paths of the Parc de la Citadelle for free; for the fortifications themselves there are guided underground tours through more than five kilometres of tunnels and casemates. The view from the top, across the city and the wooded Meuse valley, is the best in the province. The Terra Nova visitor centre on the site sets out the long, bloody history with a refreshing lack of triumphalism.

A free funicular runs up from the Sambre quay (since 2021), or you can walk up through the gardens — about twenty minutes from the river.

A story
Vauban once called Namur the "termite mound of Europe" — every European power that ever fought in the Low Countries took a turn besieging it. Louis XIV captured it in 1692; William III took it back three years later, in a siege whose details made it into Sterne's Tristram Shandy as Uncle Toby's obsession. The fortress was finally dismantled as a working stronghold only in 1891.
