You might recognize Chatsworth House, the Derbyshire home of the Duke and Duchess of Devonshire, as Mr. Darcy’s country estate in the 2005 version of Pride and Prejudice, starring Keira Knightley as Elizabeth Bennet. In conjunction with Sotheby’s 275-year anniversary and the opening of its expanded New York galleries, “Treasures from Chatsworth” features more than 40 masterworks from the fabled house. Free and open to the public, the exhibition is designed by David Korins, the set designer for Broadway hits Hamilton and Dear Evan Hansen. The selected art spans centuries, from Rembrandt to Lucian Freud, and includes a pen-and-ink sketch by Leonardo da Vinci, plus generations of jewels, garments, and furniture, amounting to half a millennium of shrewd family collecting. On view alongside “Treasures from Chatsworth,” a selling exhibition, “Inspired by Chatsworth,” offers a series of works available for immediate purchase through its closing date, September 13. —Julia Vitale
