Kedleston Hall is an English country house in Derbyshire, approximately four miles north-west of Derby, and is the seat of the Curzon family. Today it is a National Trust property.
The Curzon family have owned the estate at Kedleston since at least 1297 and have lived in a succession of manor houses near to or on the site of the present Kedleston Hall. The present house was commissioned by Sir Nathaniel Curzon (later 1st Baron Scarsdale) in 1759. The house was designed by the Palladian architects James Paine and Matthew Brettingham and was loosely based on an original plan by Andrea Palladio for the never-built Villa Mocenigo. At the time a relatively unknown architect, Robert Adam was designing some garden temples to enhance the landscape of the park; Curzon was so impressed with Adam's designs, that Adam was quickly put in charge of the construction of the new mansion.

External design
The neoclassical interior of the house was designed by Adam to be no less impressive than the exterior. Entering the house through the great north portico on the piano nobile, one is confronted by the marble hall designed to suggest the open courtyard or atrium of a Roman villa. Twenty fluted alabaster columns with Corinthian capitals support the heavily decorated, high-coved cornice. Niches in the walls contain classical statuary; above the niches are grisaille panels. The floor is of inlaid Italian marble. Matthew Paine's original designs for this room intended for it to be lit by conventional windows at the northern end, but Adam, warming to the Roman theme, did away with the distracting windows and lit the whole from the roof through innovative glass skylights.
If the hall was the atrium of the villa, then the adjoining saloon was to be the vestibulum. The saloon, contained behind the triumphal arch of the south front, like the marble hall rises the full height of the house, 62 feet to the top of the dome, where it too is sky-lit through a glass oculus. Designed as a sculpture gallery, this circular room was completed in 1763. The decorative theme is based on the temples of the Roman Forum with more modern inventions: in the four massive, apse-like recesses are stoves disguised as pedestals for classical urns. The four sets of double doors giving entry to the room have heavy pediments supported by alabaster columns, and at second floor height, grisaille panels depict classical themes.
From the saloon, the atmosphere of the 18th-century Grand Tour continues throughout the remainder of the principal reception rooms on the piano nobile, though on a slightly more modest scale. The "principal apartment", or State bedroom suite, contains fine furniture and paintings as does the drawing room with its huge Venetian window; the dining room, with its gigantic apse, has a ceiling that Adam based on the Palace of Augustus in the Farnese Gardens. The theme carries on through the library, music room, down the grand staircase (not completed until 1922) onto the ground floor and into the so called "Caesar's hall". On the departure of guests, it must sometimes have been a relief to vacate this temple of culture and retreat to the relatively simple comforts of the family pavilion.
Also displayed in the house are many curiosities pertaining to Lord Curzon, Viceroy of India at the beginning of the 20th century, including his collection of Far Eastern artifacts. Also shown is Lady Curzon's Delhi Durbah Coronation dress of 1903. Designed by Worth of Paris, it was known as the peacock dress for the many precious and semi-precious stones sewn into its fabric. These have now been replaced by imitation stones; however, the effect is no less dazzling.
In addition to that described above, this great country house contains collections of art, furniture and statuary. Kedleston Hall's alternative name, The Temple of the Arts, is truly justified.
