Carboniferous tuff, a volcanic rock formed over 300 million years ago, has been used by artists and civilizations to create breathtaking outdoor sculptures. These works of art not only highlight the durability and beauty of tuff but also connect us to ancient geological history. Among the most famous Carboniferous tuff sculptures is the "Great Sphinx of Giza," though primarily limestone, its restoration parts include tuff elements. Another notable example is the "Moai Statues" of Easter Island, carved from compressed volcanic ash, showcasing the resilience of tuff. In modern art, the "Volcanic Guardians" in Iceland’s Reykjanes Peninsula are striking tuff sculptures blending nature and creativity. These masterpieces demonstrate how Carboniferous tuff continues to inspire awe across millennia.
