Tlalnepantla de Baz - The Municipality

The Municipality

The city contains 98.37% of the municipality's population, although there are extensive areas in localities outside the city with relatively low population density, particularly in its eastern zone. The city of Tlalnepantla has governing jurisdiction over only four other communities: Puerto Escondido (Tepeolulco Pto. Escondido), Colonia la Agüita Sección las Maravillas, Ejido de Tenayuca (Cola de Caballo), and Ejido San Pedro Xalostoc (El Cuervo). Less than 2% of the municipality's population is located outside of the city proper.

The municipality was created in 1978 with the name of Tlalnepantla de Baz to honor Dr. Gustavo Baz Prada (1894–1987) who was a Zapatista, governor of the State of Mexico and dean of the National Autonomous University of Mexico. The municipality is made of two areas which are not continuous (the Zona Poniente, with a population of 653,453, and the Zona Oriente 19°33′07″N 99°05′53″W / 19.55194°N 99.09806°W / 19.55194; -99.09806, with a population of 10,772, which are divided by the Gustavo A. Madero borough of the Distrito Federal). The total municipal area is 83.48 km². The eastern side borders Ecatepec de Morelos city and the Gustavo A. Madero borough of Mexico City, and the western borders Naucalpan de Juarez Municipality on the southwest, Atizapán de Zaragoza Municipality on the west, Cuautitlán Izcalli Municipality and Tultitlán Municipality on the north, the Gustavo A. Madero borough on the east, and the Azcapotzalco borough on the south.

The three most important rivers in the municipality are:

• Río de los Remedios
• Río San Javier
• Río Tlalnepantla

The Sierra de Monte Alto is in the city itself but other significant elevations in the municipality include: Cerro del Tenayo, Cerro Grande and Cerro de la Cruz.

Significant locations within the municipality include the communities of San Jerónimo Tepetlacalco, Xocoyahualco, San Pablo Xalpa, San Bartolo Tenayuca, San Andrés Atenco, San Pablo Barrientos and San Juan Ixhuatepec.

The archaeological zones of Tenayuca and Santa Cecilia Acatitlán are located here as well, each of which has a museum. The pyramid at Tenayuca served as the model of the Templo Mayor in Tenochtitlan (now Mexico City).
