Whaddon Hall

The first manor house was built on the site in the 11th century. The present house was built in 1820, replacing a house which was demolished in the late 18th century. It was once home to the Selby family , whose ancestor William Lowndes built the larger and grander Winslow Hall.
During the Second World War Whaddon Hall served as headquarters of Section VIII of the Secret Intelligence Service , under the command of Brigadier Richard Gambier-Parry. The "Station X" wireless interception function was transferred here from Bletchley Park in February 1940. That facility, known as Main Line, served in a number of capacities, the most critical the sending of Ultra intelligence from Bletchley Park to officers in the field. The term Ultra was used to convey the status of the intelligence which was considered to be above Top Secret. It consisted of information that was gathered by breaking encrypted radio communications.
