Bawdsey Manor stands at a prominent position at the mouth of the River Deben close to the village of Bawdsey in Suffolk, about 75 miles north-east of London.
Built in 1886, it was enlarged in 1895 as the principal residence of Sir William Cuthbert Quilter. Requisitioned by the Devonshire Regiment during World War I and having been returned to the Quilter family after the war, it was purchased by the Air Ministry for £24,000 in 1936 to establish a new research station for developing the Chain Home RDF (radar) system. RAF Bawdsey was a base through the Cold War until the 1990s.
The manor is now used by PGL for courses and children's holidays. There is a small museum in the radar transmitter block.
