Wrotham Park, Hertsmere, Hertfordshire is a neo-Palladian English country house, designed by Isaac Ware in 1754 for Admiral John Byng, the fourth son of Admiral Sir George Byng, which remains in the family at the heart of a 2,500 acres (10 km2) estate seventeen miles (27 km) from Hyde Park Corner. It is one of the largest private houses inside the M25 motorway.
Originally part of an estate known as Pinchbank, first recorded in Middlesex in 1310 and owned in the 17th and early 18th centuries by the Howkins family, the property passed to Thomas Reynolds, a director of the South Sea Company, who renamed the estate Strangeways. His son, Francis, sold the property to Admiral Byng, who changed the name to Wrotham Park in honour of the original family home, Wrotham, in Kent.
