Harewood House. Harewood House is a country house in Harewood near Leeds, West Yorkshire, England. Designed by architects John Carr and Robert Adam, it was built, between 1759 and 1771, for wealthy plantation and slave owner Edwin Lascelles, 1st Baron Harewood. The landscape was designed by Lancelot Capability Brown and spans 1,000 acres at Harewood. Still home to the Lascelles family, Harewood House is a member of the Treasure Houses of England, a marketing consortium for ten of the foremost historic homes in the country. The house is a Grade I listed building and a number of features in the grounds and courtyard have been listed as Grade I, II and II*. The Harewood estate was created in its present size by the merging of two adjacent estates, the Harewood Castle estate based on Harewood Castle and the Gawthorpe estate based on the Gawthorpe Hall manor house. The properties were combined when the Wentworths of Gawthorpe, who had inherited that estate from the Gascoignes, bought the neighbouring Harewood estate from the Ryther family. The combined estate was subsequently sold to the London merchant Sir John Cutler in 1696, after whose death it passed to the Boulter family. They in turn sold it to the Lascelles in 1721. The Lascelles family claim to have arrived in England with William the Conqueror, during the Norman Conquest of England. The family had settled in Yorkshire by 1315 as the de Lascelles. Prosperous members of the county gentry, the Lascelles served as members of parliament and held prominent military positions. In the late seventeenth century the family purchased plantations in the West Indies, and the income generated allowed Henry Lascelles to purchase the estate in 1738; his son, Edwin Lascelles, 1st Baron Harewood, who was a wealthy plantation and slave owner, built the house between 1759 and 1771 to replace Gawthorpe Hall, the original manor house on the estate. Edwin initially employed the services of John Carr, an architect practising in the north of England and previously employed by a number of prominent Yorkshire families to design their new country houses. The foundations were laid in 1759, with the house being largely complete by 1765. The fashionable Robert Adam submitted designs for the interiors, which were approved in 1765. Adam made a number of minor alterations to Carr's designs for the exterior of the building, including internal courtyards. The house remained largely untouched until the 1840s when Sir Charles Barry was employed by Henry Lascelles, 3rd Earl of Harewood, the father of thirteen children, to increase the accommodation. Barry added second storeys to each of the flanking wings to provide extra bedrooms, removed the south portico and created formal parterres and terraces. In 1922, Henry Lascelles, Viscount Lascelles married Mary, Princess Royal, the only daughter of George V. Initially living in the nearby Goldsborough Hall, the couple moved permanently into Harewood House at the death of Henry's father in 1929. The house is the family seat of the Lascelles family, and home of David Lascelles, the eighth Earl. During the Second World War, the house acted as a resident convalescent hospital but by the late 1940s, the Princess Royal and her family had moved permanently back to Harewood, where the house and gardens were regularly opened to the public and regularly holding musical concerts connected with musical establishments including the Yorkshire Symphony Orchestra and the Leeds Musical Festival, the latter of which the Princess was patron. Her son, Lord Harewood, who was living at Harewood, was both a member of the Leeds Music Festival's Executive Committee and a patron of the Yorkshire Symphony Orchestra's concerts. Today, the house and grounds have been transferred into a trust ownership structure managed by Harewood House Trust and are open to the public for most of the year. Harewood won a Large Visitor Attraction of the Year award in the 2009 national Excellence in England awards. Harewood houses a collection of paintings by masters of the Italian Renaissance, family portraits by Sir Joshua Reynolds, John Hoppner and Sir Thomas Lawrence, and modern art collected by the 7th Earl and Countess. Changing temporary exhibitions are held each season in the Terrace Gallery. Catering facilities in the house include Michelin-starred fine dining. As well as tours of the house and grounds, Harewood has more than 100 acres of gardens, including a Himalayan garden and its stupa, an educational bird garden, an adventure playground and the historic All Saints' Church with its alabaster tombs. From May 2007 to October 2008 the grounds contained Yorkshire's first planetarium, the Yorkshire Planetarium.
