is a classical edifice from 1695, moved to its present site at the northern end of the broad walk in 1760. It contains a statue of the goddess Flora by Caius Gabriel Cibber. The West Garden – now the family's private garden with modern planting in a three-section formal structure – is mainly a creation of the 1st Duke's time, but the layout is not original. 4th Duke's garden (1755–64) The 4th Duke commissioned the landscape architect, Lancelot "Capability" Brown to transform the garden in the fashionable naturalistic landscape style of the day. Most of the ponds and parterres were turned into lawns, but as detailed above several features were spared. Many trees were planted, including various American species imported from Philadelphia in 1759. The main aim of the work was to improve integration of the garden and park. Brown's 5.5 acre (22,000 m2) Salisbury Lawns still form the setting of the Cascade. 6th Duke's garden (1826–58) In 1826 a 23-year-old named Joseph Paxton, who had trained at Kew Gardens, was appointed head gardener at Chatsworth. The 6th Duke had inherited Chatsworth 15 years earlier and till then shown little interest in improving the neglected garden, but he soon formed a productive and extravagantly funded partnership with Paxton, who proved to be the most innovative garden designer of his era, and remains the greatest single influence on Chatsworth's garden. Features that survive from that time include: The Rockeries and The Strid: In 1842 Paxton began work on a rockery of a gargantuan scale, piling rocks weighing several tons one on top of another. One was described thus by Lord Desart in the 1860s: "In one place a sort of miniature Matterhorn apparently blocked the path but with the touch of the finger it revolved on a metal axis and made a way to pass." It is now locked in place to comply with health and safety regulations. Another rock is so balanced that it can be swayed with little pressure. Two rocks are named after the Queen and Prince Albert and another after the Duke of Wellington, all of whom visited Chatsworth in the 6th Duke's time. The Wellington Rock, a structure of several piled rocks, is high. A small waterfall drips over it into a pond. Sometimes in winter the water freezes, creating icicles. The water flows into a pond created by Paxton called 'The Strid', named after a
