A collection of objects relating to the career of Lord Castlereagh (later 2nd Marquess of Londonderry), now remembered as one of Britain's most important foreign secretaries, including the set of chairs used by the 1815 Congress of Vienna delegates (Wellington and Talleyrand amongst them) and a bust of Helen of Troy by Antonio Canova. A fine collection of paintings, including Grand Tour portraits of Robert Stewart (later 1st Marquess of Londonderry) by Anton Rafael Mengs and of Alexander Stewart by Pompeo Batoni; many portraits of the family by Sir Thomas Lawrence whose career was bolstered by his association with Robert, Viscount Castlereagh and his half-brother Sir Charles Stewart; equestrian paintings, including George Stubbs' 'Hambletonian Rubbing Down' painted after the horse's greatest win at Newmarket; important 20th-century portraits commissioned from the most prominent portraitists of the day including Philip Alexius de László de Lombos, Sir John Lavery and Edmond Brock. Brock's group portrait 'Circe and the Sirens', which depicts Edith, Marchioness of Londonderry and her three youngest daughters, captures the magical and creative spirit of Mount Stewart in the 1920 – the heyday of the house. The library contains many 20th century books, as well as books from the 18 and 19th centuries, owned and read by all the key members of the family. The 20th-century book collection was formed by Charles and Edith, 7th Marquess of Londonderry and his wife. Charles was a politician and writer; his wife created the gardens at Mount Stewart and her library reflects her interests in Irish and Scottish literature, history, archaeology, mythology, horticulture and design, as well as her own writings.
