Citadel of Namur

The citadel of Namur is one of the largest citadels in Europe. Its vast network of underground passages earned it the nickname "The termite mound of Europe" by Napoleon I. A must-see place with a magnificent view of the Meuse Valley.

Already in the Gallo-Roman era, in the 1st century u. Z., there was an archaeologically proven settlement in the area of today's Namur. The city was built in a strategically important place.

The first fortification, a wall with a double row of palisades, was built before 890. Bérenger is the first count of Namur to be documented from 925, but it is only from 974 that it is ensured that the counts made the place their main residence. They settled on the mountain spur above the confluence of the Meuse and Sambre.

When Philip the Good took possession of the county of Namur in 1429 and integrated it into the Burgundian state, the military importance of the fortress increased.

In 1477, the Duchess Maria of Burgundy (daughter of Charles the Bold and granddaughter of Philip the Good) married Maximilian von Habsburg, under the influence of the French king Louis XI. to escape. This made the area part of the Habsburg countryside.

The Namur Citadel was besieged twenty times in eight centuries.
