Imagine you're going on holiday, somewhere nice and warm, Barbados or Guatamala or somewhere like that - Somewhere you need to fly to though. You buy your tickets and pack your pants and your towel, because that's all you really need in places like that, right?
Your departure date comes around, the taxi arrives and you're whisked to the airport. Upon arrival, you are calmed by soothing music, the happy smiling faces of other travellers and the carefully thought out decoration of the terminal itself. Gradiose pictures and statuary with a global, geographical theme perhaps? Aircraft through the ages? Famous people with aviation backgrounds? All things that you're quite within your rights to expect...
Not if you fly out of Denver International you aren't - On initial arrival at the airport, you are confronted by a 30' high statue of a rearing horse with glowing red eyes, the locals have entered several petitions to have it taken down, siting that it is evil - In fact, the statue actually killed it's own sculptor as it fell on him whilst it was being completed!
If you manage to make your way inside with your wits intact, passing by two gargoyles bursting out of suitcases, you come across the dedication plaque, or capstone from when the building was completed. Apart from the large, Masonic Square and Compasses in the middle, which is enough to set the consiracy nuts off all on its own (Doesn't bother me, some of the nicest people I know are Masons) it houses a time-capsule to be opened in 2094 and it has a raised dais, with a vague resemblance to a keyboard that houses a repeat of the Masonic symbol and a braille translation of the inscription. There are them that say if you press the symbols in the correct order, the door to the secret underground bunker will open.. (Did you read that in a hushed pirate voice? - You should, ir sounds much better)
There are inscriptions in the floor, including the chemical symbols for gold and silver on the side of a mine cart and the Navajo phrase 'Dzit Dit Gaii' which means 'The Mountain that is White' - The inscription 'Mt Blanca' is also repeated in various places around the terminal - A very important place in Knights Templar mythology.
But the strangest thing you'll see, in my opinion at least, are the murals - I'm not going to post them here, because they're all over the net, but I will describe a couple to you. Try to keep in mind that we're in a public space, at an international airport, in the mainland USA, not a despot's palace in an out of the way corner of what used to be the USSR or a terrorist based republic in the Middle East.
There's one that depicts a giant nazi-esque figure, wearing a gas-mask and great-coat, with a giant sword spearing the dove of peace. He's surrounded by a slew of greiving mothers holding dead babies, in the bottom corner is a poem, written by a 16 year old child who died in Auschwitz... Just what you want to see before you catch your flight to Eastern Europe. There's one where the main feature is a scene of a group mourning three people in open caskets, surrounded by extinct or nearly extinct animals whilst the rainforest burns in the background - A poigniant image, certainly - But would you display it at an airport? Yet another shows the children of the world coming together, some of them carrying a selection of swords wrapped in the flags of warring states including the Palestinian & Israeli, Indian & Pakistani and British & Irish amongst several others, standing on a fallen statue of the unidentified gas-masked villain. Strangely, some parts of the murals have been recently painted over at the request of customers...
Weird, I think you'll agree - There are other odd things about the place, for instance, from the air it bears a close resemblance to a swastika. It was paid for mainly by a private investor, to the tune of some $5 Billion. It's alleged that five pentagonal structures were built, twelve stories high and then buried and used as foundations, rather than demolished as they were not to specification. It has triple-redundant water & power systems and a ventilation systems that stretches for miles outside the airport environs. It seems to have a higher incidence of windscreen and fuselage cracks than any other airport, this has been speculated to be due to high (or possibly low) frequency pulses emanating from below the airport itself.
Of course there are more than likely perfectly reasonable explanations for all of the above, the main one being that it's posted on the Internet it's probably tosh. But do a bit of research for yourself, immerse yourself in the world of the tin-foil hat wearing brigade, see what you can find - It might keep you busy over Christmas.
