Knebworth House is a country house in the civil parish of Knebworth in Hertfordshire, England. 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 genuine 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. Its most famous resident was Edward Bulwer-Lytton, the Victorian author, dramatist and statesman, who embellished the gardens in a formal Italianate fashion. Much of the interior was redesigned by Sir Edwin Lutyens, who simplified the main parterre. A herb garden in an interlaced quincunx design was drawn by Gertrude Jekyll in 1907 but not planted until 1982. The house is open to the public together with its surrounding gardens and grounds. The grounds include an adventure playground, mini railway and dinosaur park and host various events including classic car rallies, the annual Salvo Fair of architectural salvage and, since 1974, major open air rock and pop concerts.
