A conceptual sculpture is a work of art that is created to express a specific concept or idea, rather than simply to depict an object or figure. These sculptures are often highly abstract, using unconventional materials or forms to convey their message. They may be created to provoke thought or stimulate the viewer's imagination, and can be highly thought-provoking and intellectually stimulating. Conceptual sculptures often challenge the traditional boundaries of art, pushing the viewer to reconsider their preconceptions about what art is and what it can be.
