This fascinating plaza -- a wonderful slice of Mexican life -- has arcades on one side, a Dominican church on another. A statue of the Corregidora of Querétaro, Josefa Ortiz de Domínguez, dominates the plaza. The plaza is best known for the scribes who compose and type letters for clients unable to do so. Years ago, it was full of professional writers clacking away on typewriters, and a few still ply their trade on ancient electric typewriters among a proliferation of small print shops and presses. Emperor Cuauhtémoc's palace once occupied this land, before Dominicans built their monastery here.
