Knebworth House

Knebworth House is an English country house in the parish of Knebworth in Hertfordshire, England. It is a Grade II* listed building. Its gardens are also listed Grade II* on the Register of Historic Parks and Gardens. In its surrounding park are the medieval St. Mary's Church and the Lytton family mausoleum. It was the seat of the Earl of Lytton (also Viscount Knebworth), and now the house of the family of the Baron Cobbold of Knebworth.

The grounds are home to the Knebworth Festival, a recurring open-air rock and pop concert held since 1974.

History
The home of the Lytton family since 1490, when Thomas Bourchier sold the reversion of the manor to Sir Robert Lytton, Knebworth House was originally a red-brick Late Gothic manor house, built round a central court as an open square. In 1813–16 the house was reduced to its west wing, which was remodelled in a Tudor Gothic style by John Biagio Rebecca for Mrs Bulwer-Lytton, and then was transformed in 1843-45 by Henry Edward Kendall Jr. into the present Tudor Gothic structure.

Knebworth's most famous resident was Edward Bulwer-Lytton (1803–1873), the Victorian author, dramatist and statesman, who embellished the gardens in a formal Italianate fashion. The 1st Baron's great-grandson Neville (1879–1951) married Judith Blunt, a well known horse breeder who inherited Crabbet Arabian Stud in 1917 and devoted her life to it. In 1913–1914 the house was leased for £3,000 per year by Grand Duke Michael Alexandrovich of Russia and his morganatic wife Natalia Brasova.

Much of the interior of Knebworth House was redesigned by Sir Edwin Lutyens, who married Lady Emily Bulwer-Lytton (1874–1964) – he simplified the main parterre. Lady Emily was the daughter of the 1st Earl of Lytton, who served as Viceroy of India between 1876 and 1880. A herb garden, with an interlaced quincunx design, was drawn by Gertrude Jekyll in 1907, although not planted until 1982. The grounds are also open to the public.

The 3rd Baron Cobbold lives at the house with his family. After a career in the film industry in Los Angeles, he lets production companies film on location in the house and gardens. The grounds include tourist attractions such as an adventure playground and dinosaur park and host various events including classic car rallies.

Music festival
Beginning in 1974, a recurring open-air rock and pop concert known as the Knebworth Festival has been held in the grounds. The festival first occurred in July 1974 when The Allman Brothers Band, The Doobie Brothers and other artists played to an audience of 60,000 people. Over the years the festival has featured major artists such as Pink Floyd, The Rolling Stones, Led Zeppelin, Lynyrd Skynyrd, Queen (their 1986 concert at the venue their last with Freddie Mercury), Paul McCartney, Genesis, Mike Oldfield, The Beach Boys, Deep Purple, Eric Clapton, Elton John, Dire Straits, Robbie Williams, Oasis and Liam Gallagher.
