Pueblo Culhuacán is an officially designated neighborhood of the Iztapalapa borough of Mexico City, which used to be a major pre-Hispanic city. Ancient Culhuacán was founded around 600 CE and the site has been continuously occupied since. The city was conquered by the Aztecs in the 15th century, but the Aztecs considered the city to have status with early rulers marrying into Culhua nobility to legitimize themselves. After the Spanish conquest of the Aztec Empire, the Franciscans and later the Augustinians made Culhuacán a major evangelization center, with the latter building the monastery complex which remains to this day. Today, Culhucan is fully integrated into Mexico City physically and politically. This area was designated as a "Barrio Mágico" by the city in 2011.
