Gabbro, a coarse-grained volcanic rock, has been a favored material for sculptors due to its durability and striking appearance. Among the most famous gabbro outdoor sculptures is the "Great Sphinx of Giza," though primarily made of limestone, some restorations used gabbro for its resilience. Another notable example is the "Statue of Shapur I" in Iran, carved from a single block of gabbro, standing as a testament to ancient Persian artistry.

In modern times, gabbro continues to inspire. The "Black Obelisk" in Norway, a towering gabbro monolith, reflects contemporary minimalist design. Similarly, the "Stone River" installation in Russia features gabbro slabs arranged to mimic flowing water, blending nature and art.

These sculptures highlight gabbro's versatility, from ancient monuments to modern masterpieces, proving its timeless appeal in outdoor art.
