Namur (Flem. Namen), a city of Belgium, at the confluence of the Sambre with the Meuse, 35 miles by rail SE. of Brussels. With the exception of the picturesque citadel (1784), the old fortifications have been razed since 1866, their place being taken by a cordon of seven forts. The town itself has suffered so much by war that it offers little of interest—the cathedral, completed in 1772, with the grave of Don John of Austria; the Jesuit church of St Loup (1653), a large military school, an antiquarian museum, monuments of Leopold I. and the geologist Omalius d'Halloy (1783-1875), &c. Namur is noted for its cutlery, and also manufactures firearms, leather, paper, and tobacco. Pop. (1874) 26,030; (1895) 31,600. Namur was captured by Louis XIV. in 1692, but recaptured in 1695, after a ten weeks' siege, by William III. and 'my uncle Toby.'
The province of Namur, on the French frontier, lying between Hainault and Luxembourg, has an area of 1414 sq. m. Fertile and rich in minerals, it is watered by the Meuse, Sambre, and Lesse, and traversed by wooded spurs of the Ardennes (2000 feet). Pop. (1871) 313,655; (1895) 342,700.
