Murals have long been used in communities to express solidarity and voice political opinions. As neighborhoods become increasingly diverse, complex economic and political motivations emerge for making murals that reflect new claims and contests over space. Focusing on recently designated ethnic "-towns" in the Greater Los Angeles area, the study finds that murals reveal multiple narratives and motives, including negotiations over space, identity, place-branding, and border-making as well as interethnic competition and reconciliation. It is argued that understanding the evolving functions and multivalent potentials of murals is critical for the success of place making and community planning. In particular, we draw attention to the trend of businesses and local government agencies using murals to make statements on identity and intercultural relations.
