Waddesdon Manor is a country house in the village of Waddesdon, in Buckinghamshire, England. It is located in the Aylesbury Vale, 6.6 miles (10.6 km) west of Aylesbury.
The Grade I listed house was built in the Neo-Renaissance style of a French château between 1874 and 1889 for Baron Ferdinand de Rothschild (1839–1898) as a weekend residence for grand entertaining and as a setting for his collection.
The last member of the Rothschild family to own Waddesdon was James de Rothschild (1878–1957). He bequeathed the house and its contents to the National Trust. It is now managed by the Rothschild Foundation chaired by Jacob Rothschild, 4th Baron Rothschild. It is one of the National Trust’s most visited properties, with over 390,000 visitors annually. Waddesdon Manor won Visit England’s Large Visitor Attraction of the Year category in 2017.
