Royal Air Force Station Kenley
RAF Kenley, set on the high ground of the North Downs on the southern edge of Greater London, is one of the most historically resonant airfields in Britain. Perched at around 550 feet above sea level near the village of Kenley in the London Borough of Croydon, this former Royal Air Force station played a pivotal role in the defence of Britain during the Second World War. Today it operates as a gliding and light aviation site, but its deeper significance lies in its central part in the Battle of Britain during the summer and autumn of 1940, making it a place of considerable pilgrimage for aviation historians, heritage enthusiasts, and those drawn to the quiet dignity of sites where extraordinary events once unfolded.
The airfield's origins date to the First World War, when it was established in 1917 as part of Britain's air defence network against German Zeppelin and Gotha bomber raids on London. It was one of a ring of aerodromes constructed to protect the capital, and by the end of the war it had already accumulated a modest operational history. Between the wars it was modernised and expanded, receiving permanent brick-built structures including the distinctive curved hangers and station buildings that still survive. By 1939, Kenley was home to front-line fighter squadrons and was integrated into the crucial Dowding radar and sector control system that would prove decisive in the Battle of Britain.
The events of 18 August 1940 — known among historians as "The Hardest Day" — placed RAF Kenley at the very centre of the fiercest air combat of the entire battle. On that single day, the Luftwaffe mounted a devastating concentrated attack on the station, sending both high-level bombers and an experimental low-level raiding force of Dornier Do 17s across the airfield at treetop height. The low-level attack was particularly effective: nine Dorniers swept across the airfield almost simultaneously, dropping delayed-action bombs and destroying several aircraft on the ground, wrecking hangars, cratering runways, and putting the station temporarily out of action. The defending squadrons, principally No. 615 Squadron and No. 64 Squadron, scrambled to intercept and fierce combats raged over the surrounding skies. The German losses that day were heavy enough to begin shifting the strategic balance, and Kenley's ability to resume operations within hours demonstrated the resilience of Fighter Command's infrastructure. The names of pilots lost that day, British and Commonwealth men from across the empire, are remembered on memorials at the site.
Visiting Kenley today is a quietly moving experience. The airfield itself is largely unchanged in outline from its wartime configuration — the broad flat grassed surface of the landing ground is now managed as a nature reserve by the City of London Corporation, rich in chalk downland wildflowers including orchids, and criss-crossed by public footpaths. The surviving blast pens — the curved earthwork bays where Hurricanes and Spitfires were sheltered between sorties — are still clearly visible around the perimeter, overgrown with grass and scrub but unmistakably purposeful in their shape. The original watch office and some station buildings endure in various states of preservation. Walking the perimeter on a clear day, with the wind coming up from the Weald and the distant shimmer of London visible to the north, it is not difficult to conjure the summer of 1940 and the young men who scrambled from this ground.
The surrounding landscape is surprisingly rural for a site so close to central London. Kenley sits within a belt of green space that includes Riddlesdown, Farthing Downs, and Happy Valley, all managed as open commons and nature reserves and collectively forming one of the most accessible pieces of genuine chalk downland near the capital. The nearby village of Kenley is a quiet residential suburb, and the town of Coulsdon lies just to the north. Whyteleafe and Caterham are within walking distance, and the broader Surrey Hills Area of Outstanding Natural Beauty begins just to the south, lending the whole area a green and open character that belies its suburban context.
Access to the site is straightforward for most visitors. Kenley railway station on the Thameslink line from London Bridge provides direct access, and the airfield perimeter is reachable on foot in a few minutes. There is roadside parking near the airfield entrance on Hayes Lane and limited parking along the surrounding lanes. The public footpaths across the airfield nature reserve are open year-round during daylight hours. The Kenley Revival Project, a community heritage initiative, has worked to survey, stabilise and interpret the surviving wartime structures, and periodic open days are held when additional access and guided tours are available. The best time to visit is late spring through early autumn, when the chalk grassland is in flower and the long evenings lend the old airfield a particularly atmospheric quality.
One of the lesser-known facts about Kenley is the remarkable survival of its Battle of Britain-era infrastructure in situ. While many wartime aerodromes were built over or entirely erased, Kenley's post-war use as a gliding site meant its footprint remained largely undeveloped, and the blast pens, runway traces, and dispersal areas are unusually complete. The site also contains a small but poignant memorial garden. For anyone with an interest in the Second World War, the evolution of British air power, or the surprising wildness that London's greenbelt can conceal, RAF Kenley offers a visit that is both historically substantial and genuinely beautiful in the traditional English sense — a place where meadow browns flicker over chalk turf that was once a frontline of civilisation.
