Burnham Beeches is an ancient woodland and National Nature Reserve in Buckinghamshire. The City of London bought the 540‑acre site in 1880 to protect it from development. Today its veteran beech pollards, heathland glades and moss‑covered hollows form one of the finest remaining examples of ancient woodland in Britain. Visitors are asked to stay on main paths to reduce disturbance to wildlife. Because of its beauty and proximity to Pinewood Studios, Burnham Beeches has been a popular filming location for decades.
