a town of Denmark, in the duchy of Holstein, on a narrow neck of land separating the two lakes of Great and Little Plon, 17 miles S.E. of Kiel. The situation is very pleasant and picturesque. On a hill, rising steeply out of the lake, stands the castle, occasionally the residence of the Danish monarchs. It commands an extensive view over one of the most fertile regions of Holstein, consisting of hill and dale, wood and water, meadows and corn-fields. The town itself is very ancient, having been a celebrated place as early as the time when the Vandals held this country; but except the usual public buildings it has no structures of any importance. Pop. 3000. The great lake, irregular in form, 7 miles long and 4 broad, the largest in Holstein, is fringed with wood and studded with several islets.
