United Arab Emirates (AUH/OMAA)
This is the only tower in the world that takes the form of a crescent. At 109 meters (358 feet) tall, it stands between parallel runways. The crescent design stems from the area's maritime heritage. It represents the sail of a dhow boat, a cultural icon and welcoming symbol to visitors. Abu Dhabi International Airport opened in 1968 on an island just off the Arabian Peninsula. A new airport opened on the mainland in 1982. Some 126 million passengers have traversed its halls.

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.
