THE

DUKERIES  , a name given to a district in the N.W. of Nottinghamshire, England; included within the ancient Sherwood Forest (q.v.) . The name is taken from the existence of several adjacent demesnes of noblemen, and the character of the Forest is to some extent preserved here . On the north is the Sheffield-Retford branch of the Great Central railway, serving the town of Worksop, connecting at Retford with the Great Northern railway, while on the south the Great Central railway serves the small market town of 011erton, and connects with the Great Northern at Dukeries Junction . The following demesnes are comprised in the district . Worksop Manor formerly belonged to the dukes of Norfolk . Welbeck Abbey is the seat of the dukes of Portland, to whom it came from the Cavendish family (dukes of Newcastle); the mansion is mainly classic in style, dating from the early 17th century, but with many subsequent additions; the fifth duke of Portland (d . 1879) built the curious series of subterranean corridors and chambers beneath the grounds . Clumber House, the seat of the dukes of Newcastle, is beautifully placed above a lake in a fine park . Thoresby House is the seat of the earls Manvers, to whom it came on the extinction of the dukedom of Kingston; part of this demesne is a splendid tract of wild woodland .
