Tunnel in epsom's bunker.

Bonkers about bunkers in Epsom


The Epsom and Ewell Times joined a group of bunker-busters to explore the little known World War 2 underground complex.

Located in 5 acres of private woodland on the west side of Ashley Road, Epsom can be found one of Epsom’s largest, but least known historic buildings which needs to be preserved for the future due to its local and national importance.

The development was capable of accommodating 1500 people and included staff offices, a medical treatment area, a kitchen, toilet facilities and a small bathroom.  

Although built at a cost of £1.3 million in today’s money between 1941 and 1942, one visitor to the development left after 2 nights because he considered it to be “damp, chill and dismal” inside. 

According to The Epsom and Ewell History Explorer, in 1942 people entering the development were advised to bring wraps or thick overcoats and lighting was by 12V bulkhead filament fittings served by metal conduited electric cables.  The Epsom and Ewell History Explorer also states that 40 stand-by paraffin hurricane lamps along with fresh drinking water were supplied by the Epsom and Ewell Borough.  

The Ashley Road Deep-level Shelter is an underground World War 2 air-raid shelter that has 17,000 square feet of tunnels ranging from 10-20 metres in depth (see plan kindly provided by Bourne Hall Museum) which sadly relatively few of the borough’s residents know exists.  

The spoil from the digging of the tunnels was piled up on top of them to increase the effectiveness of the shelter. 

According to a report prepared in 1992 by Building Management South East, “The shelter is formed of a grid of tunnels bored and cut into the chalk and flint sub-strata and variously lined with brickwork and metalwork. 

There are two main ventilation/access shafts, one at the north-east and another at the north-west corner of the shelter and a further shaft rises centrally from the north end”

“The entrance tunnel and all tunnel intersections are brick lined and the remaining tunnels are lined with either open mesh or galvanised corrugated iron sheeting, supported on various types of steel-sectioned portal frames.”

The speed with which the WW2 air-raid shelter was built and the documented costs associated with its construction have given rise to a lot of speculation about what may have existed on the site prior to any building work commencing and talk of a Northern Line tube tunnel extension, a place for the dead as well as an earlier air-raid shelter funded by Lady Sybil Grant the daughter of Lord Rosebery is not uncommon on the internet.  

Mr Jeremy Harte, the curator at Bourne Hall Museum does not believe, however that there is any evidence to suggest the Ashley Road Deep-level Shelter has any mysterious origins and has written to me stating that the land in question was requisitioned by Surrey County Council for a deep air raid shelter on 8 February 1941 and the tunnels were dug in undisturbed native chalk in the same year.     

Perhaps the speed with which the underground air raid shelter was constructed should not come as a surprise to anyone, after all our country was at war with Germany and the threat of bombing and a German invasion were very real.

Whilst the Ashley Road Deep-level Shelter was not completed until after the blitz, no one knew how the war would develop, so it is comforting to know the people of Epsom and Ewell were prepared and would have had somewhere to seek refuge if the threat posed by Hitler’s V1 and V2 rockets had escalated.

The Ashley Road Deep-level Shelter is now privately owned, but Hidden History Tours offer guided tours around the complex and can be contacted via their website.    

The air-raid shelter serves as a lasting reminder of the devastating impact war has on communities.
