The Plaza de la Constitución, or Zócalo, was planned out in 1529 by Juan Peláez de Berrio. During the entire colonial period this plaza was never paved, nor had sidewalks, only a marble fountain that was placed here in 1739. This was removed in 1857 to put in the kiosk and trees were planted.
The Catedral de Oaxaca, also referred to as Cathedral of Our Lady of the Assumption, is the third to be built as the first two were destroyed by large earthquakes in the 16th and 18th centuries.
The church and former monastery of Santo Domingo de Guzmán is located 4 blocks north of the Cathedral of Oaxaca. It was constructed between 1555 and 1666. It divides into two parts: the church and the former living/working areas of the monks. The front of the church is Renaissance-style, in the central relief, Saint Dominic and Hippolytus of Rome are holding up the church.
