Anti-aircraft guns on Parliament Hill, a V1 flying bomb in the ponds, allotments and deep-tube shelters — the remarkable wartime history of Hampstead Heath, and where to find its traces today.
Hampstead Heath at War: Anti-Aircraft Guns, Doodlebugs and the Home Front
During the Second World War, Hampstead Heath was not a refuge from the conflict but a working part of London's defences. Anti-aircraft guns stood on its highest ground, allotments dug into its meadows fed a rationed city, emergency water tanks were sunk into the grass to fight fires, and on at least one occasion a German flying bomb came down in its ponds. The Heath you walk across today — apparently timeless, deliberately rural — spent six years on the front line of the Home Front, and the marks of that period are still there for anyone who knows where to look.
Key Takeaways
- Anti-aircraft guns were placed on the Heath's highest points, with batteries near Kenwood House and beside Whitestone Pond
- A V1 flying bomb — a "doodlebug" — landed in one of the ponds near Parliament Hill, causing significant damage
- Across Hampstead, 467 high-explosive and incendiary bombs killed around 200 people and damaged some 13,500 homes
- The Heath was dug over for allotments under the "Dig for Victory" campaign, and emergency water tanks were built to fight fires
- Hampstead's deep tube stations — Hampstead is the deepest on the network — served as air-raid shelters
Why the Heath Mattered to London's Defence
Geography made Hampstead Heath strategically useful. Its ridge is one of the highest points in London, rising to around 134 metres at Whitestone Pond — the reason the views from Parliament Hill reach so far across the city. That same elevation made it an obvious place to site weapons intended to engage enemy aircraft before they reached the dense streets below.
This was not new in 1939. The Heath had already been pressed into national service during the First World War, when local units — the Hampstead Howitzers, the Hampstead Heavies and Queen Victoria's Rifles among them — trained on its slopes, and Kenwood House was turned into a military hospital at the suggestion of the Grand Duke Michael Michaelovitch of Russia, then living nearby. By the time the Second World War began, the idea of the Heath as a place of defence as well as recreation was already established in the local memory.
The Guns on the Hill
When the bombing of London began in earnest in 1940, weapons systems were placed at the highest points on the Heath. Anti-aircraft guns were stationed at the rear of Kenwood House and beside Whitestone Pond, where the open, elevated ground gave gun crews the clear sightlines they needed.
For residents, the guns were a mixed blessing. They offered the reassurance of active defence and the morale of hearing London fight back, but a heavy anti-aircraft battery in action is deafening, and the spent shrapnel from shells fired upward inevitably fell back to earth somewhere. Children across wartime London famously collected shrapnel fragments the morning after a raid, and the Heath's open spaces would have caught their share. The crews who manned these positions through cold nights, often for long stretches without firing a shot, were part of the everyday landscape of the wartime Heath in a way that is almost impossible to picture on a quiet afternoon today.
The Doodlebug in the Ponds
The most dramatic single incident on the Heath itself came late in the war. In 1944, Germany began launching the V1 flying bomb — the "doodlebug," named for the distinctive buzzing drone of its engine, which cut out moments before it fell. One of these came down in one of the Heath's ponds near Parliament Hill, and the explosion caused significant damage.
A V1 carried roughly 850 kilograms of explosive and detonated on impact with enormous force. That one landed in water rather than among the terraces below was, by the brutal arithmetic of the period, a piece of good fortune for the surrounding streets — though "fortune" is a relative term in a borough that suffered as Hampstead did. The chain of ponds that today draws swimmers and birdwatchers was, for one violent moment, the point of impact for one of Hitler's vengeance weapons.
The Cost Across Hampstead
The Heath was the dramatic stage, but the real toll fell on the surrounding neighbourhood. In total, 467 high-explosive and incendiary bombs fell on Hampstead during the war, causing 1,134 casualties — around 200 of them fatal — damaging some 13,500 homes and leaving roughly 3,000 people homeless.
The damage was scattered widely. A bomb near the playground severely damaged houses in Savernake Road and Estelle Road; Mansfield Road School was destroyed by a direct hit in 1944. Streets across the wider area — Broadhurst Gardens, Ardwick Road, Mortimer Crescent, Iverson Road, Fordwych Road and many others — recorded damage and casualties through the Blitz and the later V-weapon campaign. These were not abstract statistics but specific houses on specific roads, many of which were rebuilt in the post-war years in a style that still marks them out to a careful eye.
Sheltering Underground — and in the Open
Hampstead's geology gave it one unusual asset: depth. Hampstead and Belsize Park tube stations were used as air-raid shelters, and because they sit so far below the surface — Hampstead is the deepest station on the entire Underground network, a consequence of the high ground above it — they offered genuinely substantial protection.
Not everyone went down, though. Some residents did the opposite, choosing to sleep out in the open on the Heath itself to escape the bombing concentrated on the built-up city. There is something striking in that image: families carrying blankets up onto the grass, trusting open space and distance over brick and concrete, spending the night under the same sky the bombers crossed.
Digging for Victory
War reshaped the Heath's surface as well as its skies. As German submarine blockades squeezed food imports, open land across Britain was turned over to cultivation, and the Heath was no exception. Allotments had already been opened here in the First World War — near Gospel Oak Station on the King's Meadow, and near the Vale of Health pond, where the plots were known as the "Soldiers' Allotments." The Second World War's "Dig for Victory" campaign revived the practice on a large scale, with meadows that had been carefully preserved as ornamental landscape now turned over to vegetables.
Alongside the allotments, emergency water tanks were built on the Heath to help fight the fires that incendiary raids were designed to start. For a green space whose whole nineteenth-century purpose had been to remain wild and unimproved against the pressure of development, this wholesale conversion to practical wartime use was a remarkable, if temporary, transformation.
Finding the Traces Today
Most of the physical infrastructure of the war was cleared in the years after 1945 — the gun positions dismantled, the water tanks filled in, the allotments largely returned to grass. The Heath was deliberately restored to the timeless, rural character its Victorian defenders had fought to protect, and it wears its wartime history lightly.
But the traces are there for those who look. Subtle undulations in the ground near the former battery sites, the documented history of the ponds, the rebuilt sections of surrounding streets, and the deep stations still in daily use all connect to the period. Reading the landscape with this history in mind changes an ordinary walk across the Heath — the high ground stops being merely a good viewpoint and becomes the place where gun crews once scanned the sky. For the fuller sweep of how the area came to be, our journey through Hampstead's history sets the war years in their longer context.
Frequently Asked Questions
Were there really anti-aircraft guns on Hampstead Heath?
Yes. During both world wars, anti-aircraft weapons were placed on the Heath's highest ground, with batteries recorded near Kenwood House and beside Whitestone Pond, chosen for their elevation and clear sightlines over London.
Did a bomb ever hit Hampstead Heath?
Yes. Most dramatically, a V1 flying bomb — a "doodlebug" — came down in one of the Heath's ponds near Parliament Hill in 1944, causing significant damage. The wider borough of Hampstead was struck by 467 high-explosive and incendiary bombs over the course of the war.
Why were Hampstead's tube stations used as shelters?
Hampstead and Belsize Park stations sit exceptionally deep underground — Hampstead is the deepest station on the London Underground — because of the high ground above them. That depth made them unusually safe air-raid shelters.
Was Hampstead Heath used to grow food during the war?
Yes. Under the "Dig for Victory" campaign, parts of the Heath were turned into allotments, continuing a practice begun in the First World War. Emergency water tanks were also installed to help fight fires caused by incendiary raids.
Final Thoughts
It is easy to experience Hampstead Heath as a place set apart from history — a deliberately preserved scrap of countryside that seems to exist outside the city's noise and change. The war years are a useful corrective. For six years this was contested, working ground: defended, dug over, sheltered upon and, once, directly hit. Knowing that doesn't diminish the Heath's peace; if anything it deepens it, turning a pleasant green space into a place that earned its quiet. The next time you climb Parliament Hill for the view, it is worth remembering who else once stood on that summit, and why.
