Plastic outdoor sculptures have become iconic landmarks, blending art with public spaces. Among the most famous is "The Bean" (Cloud Gate) in Chicago, crafted from polished stainless steel but often mistaken for plastic due to its seamless surface. Another standout is "Balloon Dog" by Jeff Koons, a series of oversized, mirror-finished sculptures that captivate viewers with their playful yet monumental presence.

In Rotterdam, "Santa Claus" by Paul McCarthy is a controversial yet unforgettable plastic sculpture, standing 25 meters tall. The "Maman" spider sculpture by Louise Bourgeois, though often made of bronze, has plastic iterations that dominate urban landscapes with their eerie elegance.

Plastic's versatility allows artists to create vibrant, durable works like "The Umbrellas" by Christo and Jeanne-Claude, which temporarily transformed valleys with colorful canopies. These sculptures redefine public art, proving plastic's potential to inspire and provoke.
