Stockholm-Arlanda Airport, Sweden (ARN/ESSA)
The Stockholm-Arlanda Airport control tower is probably one of the first to double as a wedding location, where couples can pay for a marriage ceremony. Designed by Gert WingÃ¥rdh, the 83-meter (272-foot) tower was completed in 2001. There are two control cabs, perched like birds atop the shaft. They symbolize Hugin and Minun, two ravens from Nordic mythology, who were sent out to watch over the world. On the black and white bands, Finnish artist Silja Rantanen superimposed 2,500 words from Antoine de Saint-ExupÃ©ry's classic 1929 aviation book Southern Mail.
The photograph is a part of Art of the Airport Tower, an exhibition that explores contemporary and historical air traffic control towers in the U.S. and around the world.
