in World War I and demolished in 1920. Modern garden (1950–present) The 7th–10th Dukes made few changes to the garden, which suffered in the Second World War, but the 11th Duke and his wife were keen gardeners and oversaw a revival. Gardening personality Alan Titchmarsh wrote in 2003, "Chatsworth's greatest strength is that its owners have refused to let the garden rest on its Victorian laurels. It continues to grow and develop, and that is what makes it one of the best and most vibrant gardens in Britain." Many historical features have been immaculately restored, and unusually for a modern country-house garden, many new features have been added, including: The South Lawn limes: Double rows of pleached red-twigged limes on either side of the South Lawn, which were planted in 1952 and removed in 2014 The Serpentine Hedge: A wavy-hedged beech corridor from the Ring Pond to the bust of the 6th Duke. It was planted in 1953. The Maze: planted with 1,209 yews in the centre of the site of the former Great Conservatory in 1962. Two flower gardens occupy the rest of the site. The Display Greenhouse (1970): Modern in style, but unobtrusively sited behind the First Duke's greenhouse. It has three climate zones: tropical, Mediterranean and temperate. Public access is limited but groups may book tours and there are first-come-first-served tours on a few days each season. The Cottage Garden: Inspired by an exhibit at the 1988 Chelsea Flower Show. A front garden of flower beds bordered by box leads to the "kitchen/dining" room with furniture covered with plants. There is a bedroom in the same style on the upper level. The Kitchen Garden: a productive fruit and vegetable garden with decorative features. It was created behind the stables in the early 1990s. Chatsworth's original kitchen garden covered and was by the river in the park. Modern sculpture includes such pieces as War Horse and Walking Madonna by Dame Elisabeth Frink, and 14 bronze portrait heads by Angela Conner. The Sensory Garden is accessible to the disabled and features many fragrant plants. It was opened in 2004 by the then Home Secretary David Blunkett. Quebec: A part of the garden to the south and west of the canal pond that was, until 2006, a neglected and dank area covered with Rhododendron ponticum. This is now an extension to the Arboretum walk, with a path along the top
