In Tehran, the abandoned US embassy has been turned into a museum that is rarely open to the public. But we're in luck, and treated to a tour with a young guide who loses no opportunity to expound on the sins of what is now known as the "US den of espionage".
It's a ghostly place, both forlorn and bleakly comic. The printers, shredders and encrypting machines have the dusty, derelict look of objects stuck in limbo. They're not old enough to be called antiques, but so hopelessly outmoded that they've become clunky symbols of a technological era so much less sophisticated than our own. They evoke thoughts of Ben Affleck's 2012 movie, Argo, which gave us Hollywood's view of the Iranian hostage crisis. It captured the frantic scramble to destroy the embassy's cache of classified documents before it was stormed in 1979 by a horde of angry students, who called themselves the Muslim Student Followers of the Imam's Line.
A glass case contains photographs of the embassy staff on "conquering day", as the museum calls it. With hands on heads, a group is being led from the building. And alongside the image is a note conveying the heart-warming news that "ladies and darks" were released.
We now move on to the room where the shredding machines are kept. And here, again, are reminders of Argo and its scenes of the Iranians' attempts to put some of the shredded documents back together. Some, we're told, were completely destroyed but "Imam's follower students" managed to "recycle" others so that they could be read.
En route to the encrypting machines, we pause to study a bizarre mock-up of an embassy meeting with a trio of waxy-looking mannequins standing in for the American officials. One stares at us glassily, his blonde wig standing on end as if still stiff from some long-ago windstorm.
These days, the embassy building is part of a training centre for the Revolutionary Guard; anti-American slogans are everywhere, along with elaborate wall murals. One depicts the Statue of Liberty with teeth bared in a wolfish snarl. Another has an Iranian soldier standing on a tattered US flag while an Iranian one flutters above him. On the pavement outside are drawings with lightning bolts slicing through the Star of David and the US flag's stars and bars.
A stone sculpture by the front door has another Statue of Liberty – a stone sculpture with a set of prison bars carved into its torso. And there are more wall murals, with teetering New York skyscrapers and smoke belching out of Uncle Sam's topper.
We've had some warning of all this. On the way to the embassy we pass two multi-storey buildings with skilfully executed paintings covering two entire walls. One has a US flag with a set of skulls where the stars should be and "Down with the USA" printed across the stripes. Another is a photo-realist portrait of Obama sharing a moment with the man said to have assassinated Hussein, the third Shia imam – one of the most revered figures in Shia history – in the year 680.
All are in stark contrast to the friendliness that has greeted the Americans in our group in most of the places we've been.
When we get to the Forgery Room, we find labels outlining the CIA's work in forging the passports of other countries, Australia among them, for entry into various parts of the Middle East. Then comes the Eavesdropping and Coding Room. Here, we're informed by more labels, "phonelines relating to politicians, militaries, religious leaders" were tapped and the results encoded.
Then it's on to the inner sanctum – the sealed room from which messages were sent from the embassy to Washington.
Finally, on the way out, we pass another glass case, containing a sobering sign headed, "Students' Decision for Conquering Spying Nest". There are three key reasons: the part the embassy played in encouraging anarchy and division; the need to prevent a coup d'etat like the one in 1953 when the CIA and MI6 engineered the overthrow of the elected prime minister, Dr Mohammad Mosaddeq, who wanted to nationalise the country's oil industry; and, possibly the most important, the US decision to give sanctuary to the Shah instead of returning him to revolutionary Iran for trial. We've been fully briefed.
