Basically a form of wall-art, a mural is any piece of artwork painted or applied directly on a wall, ceiling or other large permanent surface. A particularly distinguishing characteristic of mural painting is that the architectural elements of the given space are harmoniously incorporated into the picture.
A wide range of materials can be used for making murals. Clay and fibre-glass are the more common choices; but wood, metal and glass are also used. Sometimes, wall paintings are painted on large canvases and then attached to the wall. However, whether these works can be accurately called murals is debatable.
