Banpo Bridge Moonlight Rainbow Fountain

The world's longest bridge fountain is located on the long Banpo Bridge overpassing the Han River in Seoul, South Korea. The bridge is already a curious structure, as it's designed on top of the previous Jamsu Bridge, forming the upper half of the first double-decker bridge in the country.

On both sides of the less than a mile-long (1.5-kilometers) bridge are nearly 10,000 LED lights over 3,740 feet (1,140 meters) sections. Here, 38 water pumps and 380 nozzles per side shoot out over 190 tons of water per minute. This installation, called Moonlight Rainbow Fountain, was inaugurated in September 2009 and has been recognized by the Guinness World Record.

The huge amount of water that comes out of the fountain falls down into the river underneath at a distance up to 141 feet (43 meters) horizontally and 66 feet (20 meters) vertically. The water ejected is continuously recycled by being pumped again into the fountain, making sure that the installation is eco-friendly. Also, the jets can move to the beat of the music.
