CHRISPIN 360's video: Must see Citadel of Namur -Belgium

The Citadel or Castle of Namur is a fortress in the Walloon capital city of Namur, at the confluence of the Sambre and Meuse rivers. It is originally from the Roman era, but has been rebuilt several times. Its current form was designed by Menno van Coehoorn, and improved upon by Vauban after the siege of 1692. It has been classified as a Wallonia's Major Heritage site. The original citadel dates to 937. It achieved its present extent between 1631 and 1675, when the city was under Dutch control. This section was called "Terra Nova" to distinguish it from the smaller Médiane fort built adjacent in 1542 and ensuing years. A variety of subsidiary positions were built in the 18th century. It was disestablished as a military post in 1891, superseded by a new ring of forts around Namur that were calculated to prevent the city from being attacked with artillery. This ring became the Fortified Position of Namur in the 1930s. The Citadel was used as protected space for the PFN command post.[1] Together with Dinant, Huy and Liège, the Citadel of Namur forms part of the so-called Meuse Citadels.
