History+
The origins of Kenwood House date back to the 17th century. Its current appearance was shaped by the reconstruction undertaken by architect Robert Adam between 1764 and 1779 for William Murray, the 1st Earl of Mansfield. Adam designed the estate in the neoclassical style, with the library's design considered a masterpiece of his work. In 1925, Lord Iveagh, a descendant of the Guinness family, acquired the house and its park. Two years later, he bequeathed the entire property to the British nation.
