JULIERS, a city, capital of the duchy of Juliers in Westphalia; some think this city was founded by Julius Cæsar or Julia Agrippina; but this is much questioned by others, because it is not mentioned before Antoninus's Itinerary and Theodosius's Tables. The town is small, but well fortified, and neatly built; the houses are of brick, and the streets broad and regular. The citadel is large and very strong, containing a palace of the ancient dukes and a spacious piazza. In the suburbs there is a monastery of Carthusians, nobly endowed by several dukes of Juliers. The town contains 2150 inhabitants, and there is a fine woollen manufacture in this country, and likewise another of linen. It was taken by Prince Maurice of Nassau in 1610, and by the Spaniards in 1622. It is seated on the river Roer, in E. Long. 6. 18. N. Lat. 50. 55.
