Inaugurated in 1979 and designed by a (female) Danish-Swedish architect as part of a water distribution system, this trio of towers sits on a promontory jutting into the Arabian Gulf just east of the city proper and has come to be a national icon, with their distinctive architecture featuring blue/green-tiled spheres.  Besides a water tank, the main one, rising 614 feet, also houses a lounge, a revolving observation deck, and a pair of restaurants.
