One of England's largest stately homes, it dominates the surrounding country, standing on a knoll of rising ground at the southern end of the celebrated Vale of Blandings; the Severn gleams in the distance.
The famous moss-carpeted Yew Alley (subject to the devious gravelling schemes of Angus McAllister) leads to a small wood with a rough gamekeeper's cottage, which Psmith made use of, not to write poetry as he at first claimed, but to stash stolen jewellery.
Clarence, the ninth Earl, is an amiably absent-minded old chap, who is charming because of his slow, relaxed lifestyle and the simple obsessions that make him oblivious to the absurd melodrama of his family, namely his home, gardens, pumpkins, and his champion pig, Empress of Blandings.
While all of Lord Emsworth's sisters are 'take-charge' types, Constance ("Connie") in particular has a very domineering and impatient temperament, as well as a cutting vocabulary; Clarence lives in dread of her occasional return visits to the Castle.
Blandings's ever-present butler is Sebastian Beach, with eighteen years service at the castle under his ample belt, and its other domestic servants have at various times included Mrs Twemlow the housekeeper, an under-butler named Merridew, and a number of footmen, such as Charles, Thomas, Stokes, James and Alfred.
Scottish head gardeners Thorne and Angus McAllister have tended the grounds, while George Cyril Wellbeloved, James Pirbright and the Amazonian Monica Simmons have each in turn taken care of Lord Emsworth's beloved prize pig, Empress of Blandings.
Among the most distinguished are the grumpy Duke of Dunstable; leading brain-specialist Sir Roderick Glossop; publishing magnate Lord Tilbury; the fifth Earl of Ickenham, known to all as Uncle Fred; and Percy Pilbeam, head of the Argus Enquiry Agency employed to locate the lost pig and recover Gally's manuscript of his memoirs.
The Folio Society published a six volume set The Best of Blandings consisting of Summer Lightning, Heavy Weather, Uncle Fred in the Springtime, Full Moon, Pigs Have Wings, and Service with a Smile.
