An incredible labyrinth of forgotten Second World War tunnels built beneath the White Cliffs of Dover will reopen to the public today for the first time in 40 years.

The Fan Bay Deep Shelter was carved out of chalk in just 100 days in the 1940s as part of Dover’s connected gun battery armaments aimed at foiling Nazi shipping movements in the Channel.

After remaining bricked up for more than 40 years, it will open to the public today following an 18-month project and 3,000 man hours of restoration work.

Built in 1940, the tunnels were home to gun battery teams operating on the coastline during the Second World War. Pictured is Mr Wise - one of hundreds of volunteers who helped restore the tunnels

Lying 75ft below the Kent coastline, the 3,500 sq ft of interconnecting tunnels, which are reinforced with iron girders and metal sheeting, accommodated four officers and up to 185 men during the war.

The shelter - which was personally inspected by Winston Churchill in 1941 - was decommissioned in the 1950s before being filled in with rubble and soil and abandoned during the 1970s.

Officials at the National Trust say the tunnels are a 'time capsule', giving fascinating insights into war-time life, with graffiti-covered walls, discarded ammunition and even a pools coupon found in the depths.

Following their rediscovery, 100 tonnes of rubble and soil were removed by hand in a project involving more than 50 National Trust volunteers, archaeologists, mine consultants, engineers and a geologist.

Jon Barker, visitor experience manager at the White Cliffs, said: 'This rediscovered piece of the country’s Second World War heritage is a truly remarkable find.

'There has been no public access to the tunnels for over 40 years and so they remain much as they were when they were abandoned. We’ve carried out extensive conservation work to preserve both the natural decay and authentic atmosphere of the space.'

There has been no public access to the tunnels for more than 40 years, but starting tomorrow, they will be reopened for tours

The shelter was carved out of the chalk by Royal Engineers from the 172nd Tunnelling Company in 1940. Pictured is graffiti dated January 20, 1941

The shelter was carved out of the chalk by Royal Engineers from the 172nd Tunnelling Company and had a hospital, secure store and five large chambers providing bomb-proof accommodation.

And behind the heavy security doors and the 125 steps descending to the tunnels lie poignant reminders of the tunnel’s war-time history.

Etched into the chalk inside the tunnels is a large amount of graffiti, including names of military personnel, coarse inscriptions and an intricate 3D face of a young man, possibly a portrait.

Some of the inscriptions are accompanied by the regiment of soldiers, most notably from the Royal Engineers - 1941 is the most popular date which features alongside the signatures.

Written in chalk on a steel shuttering alongside where a bunk bed once stood is the phrase 'Russia bleeds whilst Britain Blancos' - a popular slogan adopted by disaffected soldiers referring to Blanco, a substance they used to clean and colour their equipment.

Other finds included pieces of wire twisted into home-made hooks by soldiers to hang their uniforms, and a Unity Pools football coupon dated February 20, 1943, recording 14 football matches.

One of the first discoveries made by volunteers when they entered the tunnels was of a needle and thread, believed to be khaki wool, tucked into the tunnel wall.

Bullets, including British .303 cartridges and American 30 calibre ammunition rounds, were also found throughout the tunnels, often tucked into small gaps in metal sheeting.

Two rare First World War sound mirrors also form part of the site.

Regarded as one of the first early warning devices invented in Britain, sound mirrors gave advanced notice of approaching enemy aircraft but became obsolete with the invention of radar technology in the 1930s.

White Cliffs volunteer Gordon Wise said: 'Seeing the tunnels in their raw state when they were first discovered, handling artefacts and giving tours is like standing in the footsteps of history.

'To be part of the digging team, mirroring the work the Royal Engineers originally took to excavate the shelter, was very special. I can’t wait to see what visitors make of Fan Bay Deep Shelter.'

The tunnels - once manned by troops from the 203rd Coast Battery, Royal Artillery, later becoming the 540th Coast Regiment - lie beneath land bought by the National Trust in 2012 following a £1.2million public appeal.

Guides will lead hard hat and torch-lit tours deep below the White Cliffs of Dover, telling people the story of the tunnels’ creation, use and abandonment in the 1970s.

The National Trust is asking for help in identifying the men from the 172nd Tunnelling Company, the 203rd Coast Battery and 540th Coast Regiment, Royal Artillery and asking anyone with information to contact the White Cliffs.
