The Cenozoic era, spanning the last 66 million years, has gifted the world with remarkable basalt formations, often transformed into breathtaking outdoor sculptures. Among the most famous is Iceland's "Áfangar" by Richard Serra, a series of towering basalt columns arranged in a hauntingly beautiful pattern along the coast. Another iconic piece is "Basalt Columns" in Germany's Vulkaneifel region, where artists have carved intricate designs into ancient volcanic rock.

In the U.S., the "Lava Falls" installation in Arizona showcases basalt’s rugged beauty, while Japan's "Stone and Water" garden in Kyoto features polished basalt monoliths. These sculptures not only highlight the stone’s durability but also its deep connection to Earth’s geological history. Each piece tells a story of volcanic forces and human creativity, making them must-see landmarks for art and nature enthusiasts alike.
