The residence of the Duke and Duchess of Northumberland, this is one of England's most lavish stately homes. Set in a 55-acre park landscaped by "Capability" Brown, the core of the house is Tudor—it was one of the last stopping places for Henry VIII's fifth wife, Catherine Howard, and the extremely short-lived monarch, lady Jane Grey ("Queen for a day" as the saying goes—though it was actually 13), before they were sent to the Tower. It was remodeled in the Georgian style in 1761 by famed decorator Robert Adam. He had just returned from studying the sights of classical antiquity in Italy and created two rooms sumptuous enough to wow any Grand Tourist: the entryway is an amazing study in black and white, pairing neoclassical marbles with antique bronzes, and the Ante-Room contains 12 enormous verd-antique columns surmounted by statues of gold—and this was just a waiting room for the duke's servants and retainers. The Red Drawing Room is covered with crimson Spitalfields silk, and the Long Gallery is one of Adam's noblest creations. On certain Sundays and bank holidays in the summer you can take a miniature-steam-train ride in the grounds.
