Given the cache of the term ’Dulwich’, the half of Herne Hill which lies in the London Borough of Southwark rather than Lambeth has recently become the ‘North Dulwich Triangle’ which is comprised of the roads contained within the triangle bordered by Half Moon Lane, Herne Hill and Red Post Hill.
North Dulwich station itself - just about within the triangle - was designed in a hybrid classical style by Charles Barry, Jr. and built in 1868 by the London, Brighton and South Coast Railway. It is listed Grade II on the National Heritage List for England as is the K6 telephone kiosk inside the portico of the station.
