It is the perhaps the most unusual - and exclusive - museum in the world, filled with artefacts that have shaped history. But its doors are firmly shut to the public.
On display is a scale model of the compound in which Osama bin Laden was discovered in Pakistan. President Obama was shown a model before approving the raid that killed the al-Qaeda leader in 2011. "It speaks to how counter-terrorist officers look to the pattern of life of the target," explains Mr Byer.The first half of the museum moves in chronological order from the CIA's foundation in 1947 through the Cold War, with the 11 September 2001 attacks a clear pivot in the shift towards focusing on counter-terrorism, with items in display donated by some of those whose relatives died in the attacks.
The phrase "we can neither confirm nor deny" is a familiar one for those who report on intelligence agencies and its origins lie in a story detailed in the museum using never seen before items.
