The urban area of Antofagasta begins abruptly, breaking the monotony of the desert and is located in the coastal plains, south of Mejillones Peninsula and north of "Cerro Coloso". The Tropic of Capricorn passes in the north of the city, outside the urban area, which is located the Cerro Moreno International Airport. The Tropic of Capricorn Monument was opened on 21 December 2000 in celebration of this. Designed by the architect Eleonora Roman, it was created to point the Tropic of Capricorn and to work as a Solar Calendar.
