Pecos was one of the largest and strongest pueblos in the region, with a five-story structure built of stacked, mortared, and plastered stones rising at its center. Daily life there included people weaving cotton thread into pueblo designs, grinding corn, preparing meals, and making clothing, flutes, and ceramic pots. Music from bone flutes would have been heard in the pueblo, and underground ceremonial rooms called kivas were the center of pueblo life. The kiva in front of this place was used by the Pecos people for religious activities for at least two hundred years.
