Crown Fountain, Chicago

In the city's Millennium Park, the Crown Fountain functions as a gathering place, a kid's play area, and an interactive sculpture. Artist Jaume Plensa placed two giant LED screens inside glass-bricked monoliths that face each other across a wide plaza. The screens display images of 1,000 different Chicagoans, who smile at first, then pucker their lips to reveal a stream of water that "spits" into the granite pool. Meant to evoke ancient fountains with water emitting from the mouths of deities, this one is a whole lot more fun.

Main Fountain, University of Albany


The gorgeous, shallow pool that's situated in the middle of the Edward Durell Stone-designed campus is the social center of the college. It's currently undergoing a massive renovation (that's a rendering above) to repair the water tower and become more accessible to students, who treat it like a country club whenever temperatures rise. A dip in the waters was part of an annual ritual named Fountain Day, which celebrates the fountain being turned back on after the winter, though the tradition was suspended in 2011.

Ira Keller (Forecourt) Fountain, Portland


The Forecourt Fountain in Portland's Keller Fountain Park was designed in 1970 by Angela Danadjieva, a designer at Lawrence Halprin & Associates. It quickly became known one of the most beloved public spaces in the country, with critic Ada Louise Huxtable saying it "may be one of the most important urban spaces since the Renaissance." People are allowed to climb on top of the 25-foot walls and wade in the pools below (jumping between the two is not recommended).

Pier 6 Water Lab, Brooklyn


The playground at Brooklyn Bridge Park is one of the best on the planet, and this "fountain" is more than just a water wonderland—it serves as a science center for local kids, who can splash around the jets and chutes as they learn about nature and physics. The complex was designed by Michael Van Valkenburg and Associates, which also designed the surrounding park.
