and woods were planted on the horizon. These were arranged in triangular clumps, so that a screen of trees could be maintained when each planting had to be felled. Brown's plantings reached their peak in the mid-20th century and are gradually being replaced. The 5th Duke had an elegant red-brick inn built at Edensor to cater to a growing number of well-to-do travellers coming to see Chatsworth. It is now the estate office. In 1823 the Bachelor Duke acquired the Duke of Rutland's land around Baslow to the north of Chatsworth in exchange for land elsewhere. He extended the park about half a mile (800 m) north to its present limits. He had the remaining cottages of Edensor inside the park demolished, apart from the home of one old man who did not wish to move, which still stands in isolation today. The houses in Edensor were rebuilt in picturesque pattern-book styles. In the 1860s the 7th Duke had St Peter's Church, Edensor, enlarged by Sir George Gilbert Scott. The church spire embellishes the views from the house, garden and park. Inside there is a remarkable monument to Bess of Hardwick's sons Henry Cavendish and William, 1st Earl of Devonshire. St Peter's in Edensor is where the 6th, 7th, 8th, 9th, 10th and 11th Dukes and their wives are buried, not in a vault inside the church, but in individual graves marked by simple headstones, in the Cavendish family plot overlooking the churchyard. On the hills of the eastern side of the park is Stand Wood. The Hunting Tower there was built in 1582 by Bess of Hardwick. At the top is a plateau of several square miles of lakes, woods and moorland. There are public paths through the area and Chatsworth offers guided tours with commentary in a 28-seater trailer pulled by a tractor. The area is the water source for the gravity-fed waterworks in the garden. The Swiss Lake feeds the Cascade and the Emperor Lake the Emperor Fountain. The Bachelor Duke had an aqueduct built, over which water tumbles on its way to the cascade. The late Deborah, Dowager Duchess of Devonshire, was a keen advocate of rural life. In 1973 a Chatsworth Farmyard exhibit was opened in the old building yard above the stables at explaining how food was produced. There are milking demonstrations and displays of rare breeds. An adventure playground was added in 1983.
