Rising from the cusp of the Sambre and Meuse rivers, the Citadelle de Namur with its formidable Medieval walls is a sight to behold. This historically significant stone-fortress is most renowned for the siege where Belgic Gauls were defeated at the hands of the mighty Julius Caesar. It is also the site of the oldest permanent settlement in the Benelux. Its origins date back to the Roman Era and the fortress has undergone many a facelift in the 10th, 12th, 14th and 16th Centuries. Sprawled along the slope at the bank of the rivers, the Citadelle de Namur features several hauntingly beautiful corners, quaint cobbled pathways, and hidden passages tucked into its stone facade.
