[6] The Knights Hospitaller tried to acquire the estate but they were forced to surrender and in 1327 it was granted to Mary de St Pol, the Countess of Pembroke, who held the manor for 50 years.

[7] Their son Henry Stuart, Lord Darnley, who was born in the house in 1545 and educated there, married Mary, Queen of Scots, by whom he was the father of King James VI of Scotland and I of England.

[21][22] In 1714, Temple Newsam was inherited by Rich Ingram, 5th Viscount of Irvine, and his wife Anne who spent a vast fortune furnishing the house and creating the East Avenue.

[19] Between 1738 and 1746, Henry Ingram, 7th Viscount of Irvine remodelled the west and north wings of the house, creating new bedrooms and dressing rooms and the picture gallery.

[23] A painting in Leeds Art Gallery by Philippe Mercier of c. 1745 shows Henry and his wife standing in front of Temple Newsam House.

[25] Reflecting her interest in pastoral landscape design, Frances is depicted as a shepherdess in a portrait by Benjamin Wilson at Temple Newsam.

[26] Some aspects of Brown's plan depicted in paintings by James Chapman and Michael Angelo Rooker were never completed such as a large lake near the house.

[27] Charles and Frances's eldest daughter Isabella Ingram, (later Marchioness of Hertford) (d.1834) who inherited Temple Newsam, was the mistress of the Prince of Wales (later King George IV) from 1806 to 1819.

[28] Lady Hertford inherited the house in 1807; after her husband died in 1822 she spent the season in London, and the rest of the time at Temple Newsam where she involved herself in charitable works including distributing food and clothing to the local people.

[30] During the last years of Isabella's life, the canal, railway and roads encroached on the estate as well as coal mining; and she dealt with the companies setting these up.

[31] At her death in 1834, Isabella left Temple Newsam to her widowed sister, Frances Ingram Shepheard, wife of Lord William Gordon, who died in 1841.

[36] In 1922 Edward Wood sold the park and house to Leeds Corporation for a nominal sum, placing covenants over them to ensure their preservation for the future.

[37] Remains of the early 16th century house were retained in the new building, including the brickwork and bay windows in the centre of the west front.

[39] Tudor features have also been discovered beneath later layers of decoration, including Lord Darcy's crest scratched into the plaster in the Blue Damask room.

[42] Round the top of the house, letters appear in a balustrade, declaring the piety and loyalty of Sir Arthur Ingram: "All Glory And Praise Be Given To God The Father The Son And Holy Ghost On High Peace On Earth Good Will Towards Men Honour And True Allegiance To Our Gracious King Loving Affection Amongst His Subjects Health And Plenty Be Within This House"[38] The chapel in the north wing retains some 17th century features, such as armorial stained glass, probably by Henry Gyles and a carved wooden pulpit by Thomas Ventris, made around 1636, with geometric patterns, pilasters and friezes.

[23] In 1718, the steward of Temple Newsam suggested an underground service passage to link the north and south wings to the 5th Viscount, who agreed.

[44] In 1738, Henry, 7th Viscount Irwin wrote to his mother describing the neglected state of the house with windows coming away and cracked brickwork.

[45] The distinctive sphinx gate piers by Lancelot Brown constructed in 1768 were based on designs published by Richard Boyle, 3rd Earl of Burlington in 1738 and used at Chiswick House.

[23][21] In 1796, Frances Shepheard employed a Mr Johnson to alter and reface the south wing in a style which tried to copy that of Sir Arthur Ingram's original house.

The village was initially called Newmarket but then became Irwin Square on ordnance survey maps[51] and Ingram Place on census lists, but it was commonly simply known as Waterloo.

There is an established programme of restoring rooms back to known previous configurations, reversing the numerous intrusive installations and modifications that took place during the building's "art museum" phase.

[59] There are extensive gardens, with a celebrated rhododendron walk and six National Plant Collections: Aster novi-belgii (Michaelmas daisies), Phlox paniculata, Delphinium elatum (Cultivars), Solenostemon scutellarioides (sys.

[63][64] The north lodges[65] and the nearby boundary walls[66] are Grade II listed as are several buildings at Home Farm: the dovecote and laundry,[67] a barn[68] and the farmhouse.

[69] Several other structures at Temple Newsam are also Grade II listed, these are the Sphinx Gates,[70] the walled garden,[71] a cast-iron fountain,[72] and a stone bridge.

[73] There are substantial holdings of fine and decorative art which are designated by the Department of Culture, Media and Sport (DCMS) as being of national significance.

[75] The Picture Gallery, itself an important example of early English rococo style,[76] includes artwork brought back from Europe by Edward 4th Viscount in the first decade of the 18th century,[19] and ranging from paintings of seascapes, landscapes and battle scenes by Antonio Marini, whose portrait is also on display.

[76] The suite's floral upholstery was made using techniques including petit point needlework and French knots to depict sunflower seeds on the daybed.

[77] The Temple Newsam Picture Gallery Suite was the focus of a project in 2021 using microscopic technology to magnify the needlework up to 1,000 times and reveal detail down to individual threads.

When interviewed on Front Row, BBC Radio 4, November 2004 Fisher placed Temple Newsam House in the top three non-national museums in the country, along with Birmingham's Barber Institute and the Dulwich Picture Gallery.

An amphitheatre near the stables block is used for occasional open-air theatre performances, and the fields to the north of the Home Farm are used for various events such as Steam Fairs and Dog Shows.
