CLEVES, a city of Germany, in the duchy of Cleves, of which it is the capital. It stands upon a pleasant hill, about three miles from the Rhine, with which it communicates, by means of a canal which is large enough for great barges. The castle stands upon a mountain, and, though old, is very agreeable. Calvinists, Lutherans, and Roman Catholics, are all tolerated in this city. E. Long. 5. 36. N. Lat. 51. 40.
