Magdalena Contreras is one of the 16 territorial demarcations of Mexico City, located to the south-west. It limits to the north with the Alcaldía de Álvaro Obregón, to the west with the State of Mexico and to the south with the City Hall of Tlalpan. The Mayor of La Magdalena Contreras is one of the main green lungs of the capital because it is one of the delegations with more green areas in the CDMX. It has important places of social, tourist, ecological, cultural and religious interest. Through the delegation runs the last living river of the city, which is called Rio Magdalena.
