History.
Kneesworth Hall has had a varied and diverse usage in its history. In the middle of the 16th century, William Bolnest created a nine roomed red bricked house, which his son Thomas Bolnest also lived in. In 1597, the house was purchased by Geoffrey Nightingale (b.1550 d.1619), father of Sir. Thomas Nightingale, 1st Baronet of Newport Pond (b.1577 d.1645). Geoffrey was a lawyer who provided estate management for various landed gentry. In 1600, he acquired 200 acres of land in Bassingbourn and Kneesworth belonging to the Burman family, and another 360 acres from the Thomas Bolnest. By 1695, his grandson, Edward Nightingale (b.1658 d.1723), owned approximately 725 acres, who had also acquired an additional 100 acres from Sir. Henry Pickering, Lord of Whaddon. By 1797, Sir. Edward Nightingale, 10th Bart (b.1760 d.1804), had a real estate portfolio of 880 acres in Kneesworth, 130 acres of land leased from Christ's College, and 200 acres in Bassingbourn. His son, Sir. Lt. Charles Etherlston Nightingale, 11th Bart (b.1784 d.1843), sold a significant majority of the portfolio including the rights to Kneesworth Hall in 1814 and 1831, which totalled 897 acres. The purchaser, William Mason, retained Kneesworth Hall from 1832 to 1848. In 1849, it passed to Biscoe Hill Wortham (d.1895). Sydney Holland, 2nd Viscount Knutsford bought the estate in 1900, which included 49 acres of parkland. By 1904, he had rebuilt the hall into an Edwardian mansion by employing Robert Plumbe, a local architect. After he died in 1931, it was occupied by his widow Mary Holland who passed in 1947. In 1948, it was sold to the Cambridge Education Authory and converted into a Boys Approved School for children with high IQs in collaboration with the University of Cambridge and the Home Office. By this time, the estate had close to 200 acres of land, with 9 cottages and a mill house, including the mansion itself. In 1985, it was purchased by the AMI Healthcare Group and later converted into a psychiatric hospital.
