number of large satellite dishes, which were constructed in the 1960s, initially to televise the 1968 Olympic Games. These dishes would give the city the nickname of “City of the Satellites.” Today, they provide various services. The two largest satellite dishes are 32 meters in diameter and weigh 330 tons each. These provide international service. A third is 15 meters in diameter and links the country with networks in the United States. The last is only 7 meters and is national. These dishes are the largest and the most important in Mexico. One distinctive neighborhood whose origins can be traced back to the original founding of the Spanish city is Colonia Francisco I.

It is located in the Trans-Mexican Volcanic Belt in the Sierra Hidalgo, as it begins its descent to the Gulf of Mexico. It is mostly valley floor with some peaks. This relatively flat surface is mostly of light volcanic rock cut with ravines, small canyons, large hills and volcanoes.
