Devonian basalt, a volcanic rock formed over 350 million years ago, has been a favored material for sculptors due to its durability and striking appearance. Among the most famous outdoor sculptures crafted from this ancient stone is "The Spire of Dublin," a towering 120-meter needle-like structure that symbolizes Ireland's resilience. Another notable piece is "Basalt Columns" by Andy Goldsworthy, where the artist arranges hexagonal basalt pillars in mesmerizing patterns, blending art with natural geology.

In Iceland, the "Imagine Peace Tower" by Yoko Ono incorporates basalt in its serene design, while Japan's "Stone and Light" sculpture in Sapporo uses polished basalt to reflect the surrounding landscape. These works highlight the versatility of Devonian basalt, transforming rugged geological formations into breathtaking public art. Whether as standalone installations or integrated into urban spaces, these sculptures celebrate the timeless beauty of Earth's volcanic history.
