Who doesn’t love a fountain? Fountains are extravagantly, unceasingly festive. Whether it’s the continuous trickle of Rome’s Trevi fountain, or the exuberant bursts of the Bellagio fountain in Las Vegas, a fountain is a thing of joy. Some fountains are flashy and show-offy, like Seoul’s Banpo Bridge Moonlight Rainbow. Others, like New York’s Bethesda fountain in Central Park, are stately and majestic.
