Waddesdon Manor is a country house in the village of Waddesdon, in Buckinghamshire, England. The house was built in the Neo-Renaissance style of a French château between 1874 and 1889 for Baron Ferdinand de Rothschild (1839–1898). The Baron, a member of the Rothschild banking dynasty, chose as his architect Gabriel-Hippolyte Destailleur. The last member of the Rothschild family to own Waddesdon was James de Rothschild. He beqeathed the house and its contents to the National Trust in 1957. Today, following an extensive restoration, it is administered by a Rothschild charitable trust that is overseen by Jacob Rothschild, 4th Baron Rothschild. The house was built on a barren hilltop overlooking Waddesdon village. In 2007–08 it was the National Trust's second most visited paid-entry property, with 386,544 visitors.
The Baron wanted a house in the style of the great Renaissance châteaux of the Loire Valley. Destailleur was already experienced in working in this style, having overseen the restoration of many châteaux in that region, in particular that of the Château de Mouchy. Through Destailleur's vision, Waddesdon embodied an eclectic style based on the châteaux so admired by his patron, Baron Ferdinand. The towers at Waddesdon were based on those of the Château de Maintenon, and the twin staircase towers, on the north facade, were inspired by the staircase tower at the Château de Chambord. However, following the theme of unparalleled luxury at Waddesdon, the windows of the towers at Waddesdon were glazed, unlike those of the staircase at Chambord. They are also far more ornate.
The structural design of Waddesdon, however, was not all retrospective. Hidden from view were the most modern innovations of the late 19th century including a steel frame, which took the strain of walls on the upper floors, which consequently permitted the layout of these floors to differ completely from the lower floors. The house also had hot and cold running water in its bathrooms, central heating, and an electric bell system to summon the numerous servants.
Once his château was complete, Baron Ferdinand installed his extensive collections of French 18th-century tapestries, boiseries, furniture and ceramics, English and Dutch paintings and Renaissance works of art. Extensive landscaping was carried out and the gardens enhanced with statuary, pavilions and an aviary. The beautiful Proserpina fountain was brought to the manor at the end of 1800 from the Palace of the Dukes of Parma in northern Italy: the Ducal Palace of Colorno. The grounds were laid out by the French landscape architect Lainé. An attempt was made to transplant fully-grown trees by chloroforming their roots, to limit the shock. While this novel idea was unsuccessful, many very large trees were successfully transplanted, causing the grounds to be such a wonder of their day that, in 1890, Queen Victoria invited herself to view them. The Queen was, however, more impressed by the electric lighting in the house than the wonders of the park. Fascinated by the invention she had not seen before, she is reported to have spent ten minutes switching a newly electrified 18th-century chandelier on and off.
When Baron Ferdinand died in 1898, the house passed to his sister Alice de Rothschild, who further developed the collections. Baron Ferdinand's collection of Renaissance works and a collection of arms were both bequeathed to the British Museum as "The Waddesdon Bequest". During World War II, children under the age of five were evacuated from London and lived at Waddesdon Manor.
Following Alice de Rothschild's death in 1922, the property and collections passed to her great-nephew James A. "Jimmy" de Rothschild of the French branch of the family, who further enriched it with objects from the collections of his late father Baron Edmond James de Rothschild of Paris.
When James de Rothschild died in 1957, he bequeathed Waddesdon Manor, 200 acres (0.81 km2) of grounds and its contents to the National Trust, to be preserved for posterity. The Trust also received their largest ever endowment from him: £750,000 (£13,461,320 as of 2010),.
A nearby ancillary property, The Pavilion at Eythrope, had been constructed for Alice de Rothschild by the architect George Devey. This became the home of James de Rothschild's widow, Dorothy de Rothschild, usually known as "Mrs James"; she took a very keen interest in Waddesdon for the remainder of her long life. Eythrope and the rest of the Waddesdon estate remain the property of her heir, the 4th Lord Rothschild.
Jacob Rothschild, 4th Lord Rothschild, has recently been a major benefactor of Waddesdon Manor through The Alice Trust, a registered charity headed by the Rothschild family. In an unprecedented arrangement, he was given authority by the National Trust in 1993 to run Waddesdon Manor as a semi-independent operation. The Trust has overseen a major restoration, and enhanced the visitor attractions. The Alice Trust has also acquired works of art to complement the existing collections at Waddesdon, such as Le Faiseur de Châteaux de Cartes by Jean-Baptiste-Siméon Chardin, added in 2007. In 2007–08 the charity had a gross income of over £13 million and assets of over £88 million.
In a burglary on 10 June 2003 by the Johnson Gang, approximately 100 priceless French gold snuff boxes and bejewelled trifles were stolen from the collection. None of them were recovered intact, though fragments of a few were found amid melted gold in the burnt wreckage of a motor vehicle close to the Manor. These irreplaceable artefacts, many encrusted with diamonds, had belonged to, among others, Marie Antoinette and Madame de Pompadour.
Several films have been shot at Waddesdon Manor, including the Carry On film Don't Lose Your Head, the Indian film Kabhi Khushi Kabhi Gham and in 2006 The Queen, in which interiors and the gardens doubled for Buckingham Palace.
It was used as the O'Connell family's home in the film The Mummy: Tomb of the Dragon Emperor.
