The "Claygate Ridge" is a distinctive, north-north-east-south-south-west oriented ridge in South London , which is largely composed of the partly silty - fine sandy upper layers of the London Clay ("London clay"), the Claygate Beds ("Claygate layers"), is formed. The border between the London boroughs of Southwark and Lewisham or Bromley runs along its ridge . The ridge stretches for around 6.5 kilometers from Forest Hill over Upper Sydenham (both in Lewisham), East Dulwich (Southwark), Crystal Palace (including Bromley) and Upper Norwood ( Croydon ). In its highest ridges, which are mainly along the road Sydenham Hill in Upper Sydenham, it reaches a height of more than 100 meters (330 feet) and allows an unobstructed view of the Thames lowland to the north. To the west of the ridge extends the wide depression of the River Wandle , and to the east that of the Pool River .

The ridge is crossed by several railway tunnels. It is also the location of two well-known transmission towers, the Crystal Palace transmitter and the Croydon transmitter .
