Whether they originate from World War II, when operations against the enemy had to be kept top secret, or from the Cold War when the threat of mass destruction was very real, underground bunkers have been a necessary tool in 20th century military defence.

Only a few of these once top secret bunkers are now open to the public; others still remain off limits. Read on to see which ones you can visit.

After the ending of the Cold War in 1991, when the threat of a nuclear strike faded away with the collapse of the Berlin Wall and the dissolution of the Warsaw Pact, the subterranean concrete bunkers that had been built to house emergency personnel during such an attack, became redundant. Some had been built much earlier and used during World War II, when the threat was more immediate but less potentially catastrophic, and revamped afterwards when the Cold War started.

Many have since been destroyed or sold off for private uses, which range from underground farming to music schools, but a few still remain and have opened their doors to the public as museums.

These once top secret bunkers with their blast doors, concealed entrances and underground habitation systems can provide a fascinating glimpse into the past, whether its the Cold War or the earlier days of World War II.

The bleak concrete walls, endless narrow tunnels and utility furniture all help to bring the threats of the past vividly into the present in a way that many museums can’t, which makes them very intriguing places to visit.

A meeting table in the Churchill War Rooms

The Churchill War Rooms, London

One of the five Imperial War Museums, this huge bunker is hidden underneath the streets of Westminster and is where Churchill and his cabinet directed World War II.

You can see the meeting rooms, operations rooms, map room, living quarters and the vast network of corridors where staff spent so much time that they rarely saw the light of day.

There is also a comprehensive exhibition about Churchill himself, filled with artefacts from his life including his hat, cigars and champagne bottles. A popular attraction, so buy your tickets online in advance. Find out more >>

Built in the 1950s and revamped in the 1980s when nuclear war became an even bigger threat, this top secret bunker was to be the home of regional government in the event of war.

It now houses the largest public display of decommissioned nuclear weapons in Europe, as well as plenty of original equipment still in place; there is also a cinema showing once secret films, a simulator that recreates conditions in the bunker when undergoing a nuclear attack, a labyrinth of corridors to explore and plenty of hands on activities.

The bunker hosts special events, has trails for kids and a cafe on site.  Read more >>

Chairs and old computers in Kelvedon Hatch Nuclear Bunker

Kelvedon Hatch Secret Nuclear Bunker, Brentwood

This relic from the Cold War was intended as a place of safety for government and council officials in the event of a nuclear attack.

Deep underground it still has all of its 1980s machinery and technology, with faxes and teleprinters in abundance.

Once secret films are on view, showing how people were expected to protect themselves when the bomb dropped, and just how futile sheltering under a table surrounded by doors and bags would be.

As well as the bunker there is a cafe and plenty of family friendly outdoor activities on offer in the woodland above. Read about a visit to the bunker >>

The Battle of Britain Bunker, Uxbridge

Here in the Operations Room deep underneath layers of steel and concrete is where the Battle of Britain was conducted saving the UK from the Luftwaffe in World War II.

Still laid out as it was, the maps, pointers and the Tote board have all survived.

An excellent new museum has recently opened above ground which tells the story of the momentous events which occurred there and explains how the creation of the Dowding System ensured that the Allies kept the upper hand. With plenty of interactive exhibits and events, the museum is family friendly. Read about a visit to the bunker >>

Also known as the Liverpool War Museum, this bunker underneath the streets of Liverpool was where the Battle of the Atlantic was directed during World War II.

Convoy routes were monitored and the enemy hunted from the Operations Room, the naval version of the Battle of Britain operations room in the bunker in Uxbridge.

300 staff once worked here day and night and a visit to the bunker is said to be a trip back in time to their lives as it has been left exactly as it was in 1945 when the war was over. The museum hosts lots of events and family friendly activities, including a half term spy club and 1940s Time Traveller weekends.  Find out more >>
