CASSEL, a town of French Flanders, and capital of a chatellany of the same name: It is seated on a mountain, where the terrace of the castle is still to be seen; and from whence there is one of the finest prospects in the world; for one may see no less than 32 towns, with a great extent of the sea, from whence it is distant 15 miles. E. Long. 2. 27. N. Lat. 50. 48.
