A wall fresco is a type of mural painting, usually painted directly onto the walls of a building. It is a form of public art that has been used since ancient times to decorate and adorn the walls of structures. The term 'wall fresco' is derived from the Italian word for 'FRESH', referring to the fact that the paint is applied while still wet. Wall frescos are often large-scale works of art that can be seen from a distance, and they often depict scenes from history or mythology.
