The Great North Wood was a natural oak woodland that started three miles (4.8 km) south-east of central London and scaled the Norwood Ridge. At its full extent, the wood's boundaries stretched almost as far as Croydon and as far north as Camberwell. It had occasional landownings as large clearings, well-established by the Middle Ages such as the hamlets of Penge and Dulwich. Twenty small fragments or re-plantations remain including Dulwich Wood, Sydenham Hill Wood, Biggin Wood and Beaulieu Heights.
