Significance

Murals are important as they bring art into the public sphere. Due to the size, cost, and work involved in creating a mural, muralists must often be commissioned by a sponsor. Often it is the local government or a business, but many murals have been paid for with grants of patronage. For artists, their work gets a wide audience who otherwise might not set foot in an art gallery. A city benefits by the beauty of a work of art.

Murals can be a relatively effective tool of social emancipation or achieving a political goal. Murals have sometimes been created against the law, or have been commissioned by local bars and coffee shops. Often, the visual effects are an enticement to attract public attention to social issues. State-sponsored public art expressions, particularly murals, are often used by totalitarian regimes as a tool of propaganda. However, despite the propagandist character of that works, some of them still have an artistic value.

Murals can have a dramatic impact whether consciously or subconsciously on the attitudes of passers-by, when they are added to areas where people live and work. It can also be argued that the presence of large, public murals can add aesthetic improvement to the daily lives of residents or that of employees at a corporate venue. Large-format hand-painted murals were the norm for advertisements in cities across America, before the introduction of vinyl and digital posters. It was an expensive form of advertising with strict signage laws but gained attention and improved local aesthetics.

Other world-famous murals can be found in Mexico, New York City, Philadelphia, Belfast, Derry, Los Angeles, Nicaragua, Cuba, the Philippines, and in India. They have functioned as an important means of communication for members of socially, ethnically and racially divided communities in times of conflict. They also proved to be an effective tool in establishing a dialogue and hence solving the cleavage in the long run.The Indian state Kerala has exclusive murals.
