A tall shining metallic arch rises above the busy streets and rolling hills of Tijuana, Baja California, giving Mexico’s westernmost city an icon to welcome visitors and to symbolize its modernity. It is called by various names, including the Arco del Milenio (Millennium Arch) or Arco de Tijuana, but officially the arch is known as the Reloj Monumental de Tijuana (Tijuana Monumental Clock). The arch has been controversial since its construction but has also become one of the city’s most important symbols in the 21st Century. 
Art is part of the discussion. The border is an issue that art can say a lot about."
Along the U.S-Mexican border various artists, using a variety of art forms, have worked to encourage the general public to reflect on the social problems caused by the border’s existence. Among the most noteworthy issues this art explores are transnational migration as well as the use of government force (such as the U.S. Border Patrol) to build up the border. The work of Nogales, Sonora, artists Alberto Morackis and Guadalupe Serrano bears witness to how public art can contribute to a greater awareness of the border’s social problems.
