The derelict military bunker at the centre of a German officer's botched plot to blow up Hitler will be opened to the public as a museum.
The Wolf’s Lair, located in the Masurian woods in northeastern Poland, has been open to the public since the end of World War II, but mainly for much criticised paintball games or as an indoor shooting range.
It was one of Hitler’s key military headquarters during the war. But is most famous as the place Colonel Claus von Stauffenberg tried to kill the dictator by placing a briefcase bomb underneath the table during a staff meeting on July 20, 1944.

The plan was to kill Hitler and replace him with a government which would negotiate a truce with the Allies, ending the war.
Having left the conference for a pre-arranged phone call, Colonel von Stauffenberg, whose fate was thrown back into the spotlight due to 2008 movie Valkyrie starring Tom Cruise, left the hut shortly before the bomb detonated. However, a staff officer had moved the briefcase shortly after von Stauffenberg’s departure which saw Hitler protected from the blast and the dictator survived with minor injuries.
Von Stauffenberg was captured and executed alongside three conspirators and all their relatives were sent to concentration camps.
A total of 200 were executed as a result of the assassination attempt.

Four months after the bomb, Wolf's Lair was destroyed by the Nazi forces as the Soviet Red army advanced in 1945. Soon after it became a tourist attraction.
Nearly 70 years later, due to lax legislation, tours of the overgrown bunkers have been less informative than the Polish Government see fit and tourists can even pose for photographs in Nazi uniforms.
‘At this moment, one does not feel the tragic dimension of this place,’ historian Tomasz Chinciski told The New York Times.

He is involved in the development of Wolf's Lair and underlines the importance of not forgetting its past.
He said: 'We need to work on new ways of telling history to make young generations want to learn it and understand it.'
The current lease of the premises is held by Wolf’s Nest, who have had the contract since the collapse of Poland’s communist regime.

Critics have called their tours of Wolf’s Lair a 'grotesque Disneyland’ operation and have called for them to stop.
In a bid to profit from ‘Nazi tourism’, Wolf’s Nest, a private company, built a restaurant, a hotel and even an indoor shooting range located in the offices of General Alfred Jodl, a Nazi Army Commander sentenced to death at Nuremberg.
But due to the remote location, Wolf’s Nest have not had much success in luring tourists to the bunker and the 600-acre complex is in despair with overgrown buildings and pathways.
In an effort to re-build the bunker, Wolf’s Nest have agreed to work with historians, according to The Independent.

Poland’s Ministry of Culture and National heritage gave strict instructions to the company that no new lease would be granted unless the company meet educational requirements.
The hideout - whose name references Hitler's nickname, 'Herr Wolff' - consisted of 80 buildings at its peak including its own power plant and a railway station.
The complex, built in 1940, was heavily camouflaged and surrounded by a minefield, which took ten years to clear after the war.

Reuters photographer Ina Fassbender recently traveled with a group to a former East German bunker near the city of Ilmenau. Built in the 1970s as an emergency shelter for the district's command unit, the bunker has now been transformed into a museum. For 109 euros ($150 USD), visitors can participate in a "reality experience" in which they wear National People's Army (NVA) uniforms and are treated as East German soldiers for a night.

Inside Mussolini's wartime bunker: First pictures of fascist leader's secret lair that he had built to protect him from RAF strike on his Rome headquarters
Pictures of Benito Mussolini's last wartime bunker that he built to protect him from an RAF bomb attack have been released for the first time.
The reinforced concrete cell, constructed 50ft below the former fascist headquarters in Rome, was so secret it was not discovered until 2011.
Historians believe Mussolini, one of Hitler's closest allies during the Second World War, had the underground bunker built for himself and his mistress Claretta Petacci.

Experts believe Mussolini's 'last bunker' was made for him and his mistress Claretta Petacci
The underground chamber was accessed through a flight of stairs, left, which led to the first room, right
The bunker built below the former fascist headquarters in Rome contained nine rooms
The nine room chamber was located so that it could be accessed within seconds of an attempted assassination attempt.
It is due to be opened to the public for the first time, two years after it was discovered under the building, which is now a museum. Engineers stumbled across the chamber when they found an iron hatch while doing structural repairs on the foundations of the headquarters.
The 80 square metre reinforced bunker opened onto a flight of brick stairs, which led down to a number of compartments.
Architect Carlo Serafini told La Stampa newspaper: 'When we saw the reinforced concrete, it was clear. It’s the twelfth bunker of Rome -- Benito Mussolini’s last bunker.
'It would have probably only been designed for Mussolini himself and one other person; more than likely his mistress, Claretta Petacci.
'The structure is still solid, it probably would have withstood a bombardment, although it would have depended on the force of the explosion. It was certainly well hidden.'
The secret bunker was built underground on the orders of Benito Mussolini, who feared an Allied bomb attack
The bunker was unfinished and there are holes in the wall meant for a sewer system and electric wiring
Mussolini and Hitler were close allies and the Italian dictator was rescued by the Nazis after he was arrested
Mussolini was eventually executed by Italian partisans in 1945
Mussolini ordered its construction in 1942 because he suspected that the RAF was planning a deadly strike on his headquarters.
However, he never stayed there but the dictator would have gone down to inspect the progress, Mr Serafini said.
The shelter overlaps with the original ruins of a Roman tower, which can still be seen.
The condition of the bunker, which has rough concrete walls, show that it was never finished.
There are holes in the wall meant for a sewer system and electric wiring, and flooring had not yet been installed, La Stampa reported.
There would have been two escape routes from the bunker - one directly to the gardens of the adjoining church of San Marco and the other to another nearby bunker under the monument to Victor Emmanuel II.
During the last few months of power the fascist leader correctly believed that his life was under threat.
In July 1943 the Commander of the RAF asked permission from Winston Churchill to eliminate the dictator, known as Il Duce - the leader.
Their plan was to simultaneously bomb his headquarters and his official residence Villa Torlonia.
But Foreign Minister Anthony Eden had doubts about the plot's success and feared the collateral damage on civilians in Rome and the city itself.
Mussolini was arrested on the King's orders in 1943 after the Allied invasion of Italy.
He was rescued from prison by the Nazis but was captured again in 1945 and executed by Italian partisans.
His body was then taken to Milan and hung upside down for a petrol station for public viewing.

Fascist dictator Benito Mussolini hid a set of secret diaries in an Italian hillside and ordered them not to be opened until 2025, the son of the man who buried them has revealed.
Mussolini, who ruled Italy from 1922 until he was executed by partisans in 1945, has long been rumoured to have kept diaries which could detail the extent of his relationship with wartime Prime Minister Winston Churchill.
There is even a theory among some Italian historians that he was executed as part of an MI6 plot to spare Britain embarrassment from revealing the truth about his closeness to Churchill.
Secrets: Benito Mussolini is thought to have written about Churchill in his diaries
Today, Rocco Della Morte, son of Guglielmo Della Morte, a wartime Italian consul in Berlin - said that in April 1945 his father met in Milan with Mussolini who gave him a locked suitcase.
Mr Della Morte, who comes from Fiumicello, close to England boss Fabio Capello's hometown of Pieris in north east Italy, said the suitcase was filled with diaries and other documents.
He said: ‘My father told me that he was called to Milan in April 1945 by Mussolini and given a suitcase. He was then told by Il Duce (Mussolini) that it should not be opened until 2025.
‘The case had the initials BM on it and was closed with a padlock. My father assumed that it was diaries and documents and not money because he was told by Mussolini not to open it for 80 years.’
Mr Della Morte said that the suitcase was buried in a valley close to the village of Campodolcino, a short distance from Italy's border with Switzerland, 100 miles from Milan.
He added: ‘Even after the war an attempt was made on my father's life - it may well have been connected to the suitcase, which he told me about in 1954 when I turned 18.
‘My father asked me to keep it secret and not to open the case until 2025 but I am now 74 years old and there are another 15 years to go. I don't know if I will reach 2025 that's why I am telling this story now.
‘Over the years I have always checked up on the suitcase, which is inside a zinc box for preservation, and it is still there in the Spluga Valley, just a few kilometers from the Swiss border.
‘Although I feel obligated to respect the promise made by my father, I've already made an arrangement for the opening of the suitcase and the publication of its contents.’
Mussolini historian Mariano Vigano, based in Rome, said: ‘They may well be genuine but until they are examined we should be very careful, prudence must prevail until they are verified.
‘There have been claims in the past regrading Mussolini diaries but none have so far proved genuine.
‘In the 1950's Mussolini's son Vittorio said that his father had given his diaries to the Japanese ambassador.
‘They were the smuggled out of Italy to Switzerland and from there we have three possibilities that they were destroyed when Japan surrendered to the Allies.
‘That they were smuggled again onto Japan and are kept in the archives in Tokyo or that they were taken to the Vatican's Secret Archive and given to Pope Pius XII and his papers will not be opened until 2028.’
Three years ago Italian senator Marcello Dell Utri claimed to have found Mussolini diaries from 1935 to 1939 but these were later proved to be forgeries.
The most famous case of forged diaries was in 1983 when a German magazine and the Sunday Times published excerpts of what it claimed were Hitler's Diaries but these were also later found to be forged.
Professor Christopher Duggan, a Mussolini expert based at Reading University, said: ‘It's very possible that documents and diaries could have been handed over to someone at the time.
‘In April 1945 there was a lot of material floating around Italy and it was being picked up soldiers as souvenirs.
‘There was chaos and all sorts of paperwork was being gathered up to try and make a deal with the Allies.
‘If true it would be interesting to see if within this suitcase there is perhaps any correspondence with Winston Churchill.
‘In 1940 Churchill was very keen for Mussolini not to enter the war and there may have been all sorts of promises and offers made.
‘This has in turn led to speculation especially among Italian historians and researchers that Mussolini may have been killed by British intelligence to prevent any potential embarrassment.
‘But as with the very famous Hitler Diaries of the early 1980's they would have to be properly examined to make sure they were not forgeries.
‘On the face of it it does seem possible but I would like to know why he is only coming forward know to reveal this. It's a long time to keep something potentially very important so secret.’
