Street art is a form of visual art created in public spaces, typically using various mediums such as spray paint, stencils, stickers, and wheatpaste. It is often created without permission and can be found on walls, buildings, sidewalks, and other public surfaces. Street art can convey social or political messages, as well as serve as a form of self-expression or artistic exploration. Street artists often use urban environments as their canvas, bringing art to the streets and making it accessible to a wide audience. Street art has become increasingly popular and recognized as a legitimate form of art, with many cities embracing and promoting street art as a cultural attraction.
