In the center of the city is found the
Catedral de Nuestra Señora de Guadalupe (Cathedral of
Our Lady of Guadalupe) and the adjacent
Capilla del Señor de los Corazones (Chapel of Our Lord of the Hearts). The Antonio de León central plaza is located next to the cathedral and the municipal palace. Its paths are lined with trees and garden spaces and an octagonal kiosk in the center. Near the town are the Cerros de las Minas, an archeological site and Las Campanas, which are calcite rocks from which drip water from a small stream. There is also the Museo Regional de Huajuapan (Regional Museum of Huajuapan) that specialized in the Mixtec cultures of this area.
Cerro de las Minas The hill now known as the
Cerro de las Minas, which dominates the valley of Huajuapan, was the site of an ancient Mixtec community. The site lies in a Mixtec region known as Ñuiñe, or lowland Mixtec. The site covers fifty hectares and was mostly inhabited by the upper social classes of the time. It was supported by farmlands in the valley below. The ceremonial area is dominated by three large constructed mounds which are eight meters high and forty meters in diameter. They are lined up and separated by large open platforms for a total length of 180 meters. The site also contain a Mesoamerican ballcourt that is about sixty meters long and fifteen meters wide. The housing units have stone foundations and either adobe or stone walls. In these foundations numerous human burials have been found. There is also a large plaza situated on the south side which contains a mass grave. In this grave, large quantities of ceramics were found of native design as well as a multicolored urn with an image of the god of wind or fire, with a brazier on its head. It is seated on a platform with four glyphs indicating location. It is now on display at the Museum of Oaxaca. The site is considered to have two stages. One is called Ñudee, which is the original Mixtec name for Huajuapan and means "place of the brave," and covers the era between 400 BCE and 250 CE. The other is called Nuiñe and covers the time period between 250 and 800 CE. Artifacts here show that during both periods, this settlement had strong ties with other Mixtec settlements in other parts of modern-day Oaxaca. The area began to decline after 800 CE, possibly due to military pressure from lords in other regions. The region would not grow again until the Spanish established their city here in the 16th century. ==Demographics==
