Tulancingo (officially Tulancingo de Bravo) is the second-largest city in the Mexican state of Hidalgo. It is located in the southeastern part of the state and also forms one of the 84 municipalities of Hidalgo, as well as the Archdiocese of Tulancingo. Located 93 km from Mexico City, this area is the most important wool textile producer in the country and was home to El Santo, Mexico’s most famous lucha libre wrestler. It is also home to the Huapalcalco archeological site, which was the forerunner to the Teotihuacan civilization. The name derives from the Nahuatl words “tule” and “tzintle” which mean “in or behind the reeds.” This is confirmed by its Aztec glyph.
