Grotto art refers to artworks created in natural caves or grottoes, often featuring prehistoric or ancient depictions of animals, human figures, and symbolic motifs. These artworks are typically associated with ancient cultures and are significant for their insights into early human creativity, spirituality, and social practices. Notable examples include the cave paintings in Lascaux, France, and Altamira, Spain, which showcase the artistic skills and cultural expressions of early humans. Grotto art is often studied in the fields of archaeology, anthropology, and art history to understand the evolution of human expression.
