On the southeastern side of the church is another great plaza that today is the town's Main Plaza. On its western side there is a wall containing big trapezoidal niches that can easily let a person stand up inside; they must have been used to keep the nobility mummies and idols that presided over ancestral ceremonies. That wall with niches has a genuine carved andesite cornice. By the middle of this plaza is a bust honoring Mateo García Pumakawa Chiwant'ito who was born in the house located in front of the bust; the house has small arch windows on the second floor. Mateo Pumakawa was Chinchero's Quechua chief, Official and Warrant Officer paid by the Spanish army; he fought against the Tupaq Amaru II Revolution helping to bring about his defeat in 1781. When being old aged he wanted to repay what he did against his people and race and joined the Angulo brothers in order to fight against the Spanish crown. But, he was defeated and hung from an arch like the ones that are seen in Chinchero, in Sicuani in 1814.
