Schist, a metamorphic rock known for its layered texture and durability, has been used for centuries to create stunning outdoor sculptures. Among the most famous is the "Schist Lion" in Delphi, Greece, a majestic guardian carved directly into the rock face. In Portugal, the schist villages of Serra da Lousã feature intricate carvings blending art with nature. Brazil’s "Pedra do Ingá" showcases ancient schist petroglyphs, while Norway’s "Troll Wall" presents dramatic natural schist formations resembling mythical creatures. These masterpieces highlight the timeless beauty of schist as a medium for artistic and cultural expression.
