Santo Domingo in Mexico City refers to the Church of Santo Domingo and its Plaza, also called Santo Domingo. Both are located three blocks north of the Mexico City Metropolitan Cathedral following Republica de Brasil Street with Belisario Dominguez Street separating the two.
Officially known as the Señor de la Expiración Chapel, the church is located on the north side of Belisario Dominguez and faces the plaza. It is all that is left from the first monastery to be established in New Spain. (The first monastery in New Spain was established by Franciscans, not Dominicans. This was not the first monastery. In fact, the Dominicans who arrived in New Spain in 1526 had to take up temporary quarters at the neighboring Franciscan convent. The citation comes from the Galindo sisters, and, like many others, it is incorrect.) This monastery was established soon after the Dominicans arrived to New Spain in 1526. They moved into houses that were donated to them by the Guerrero family, where later the Palace of the Inquisition would be built. The initially replaced the houses to found a church, living quarters and a jail for those found guilty of religious crimes. (The Dominicans were in charge of the Inquisition.) A couple of decades later, it was decided that expansion was needed and the first church on the Santo Domingo site was consecrated in 1590. Around it was built the monastery, funded by Philip II of Spain, with four patios which divided the monks and laypeople associated with the monastery by rank as well as a main hall, a rectory, a library and an infirmary. However, poor construction, the soft soil and earthquakes made rebuilding a necessity. The second church was built between 1556 and 1571. The current church the third to be built on this site. It is Baroque architecture made of pink stone, begun in 1717 and finished in 1736. The monastery and atrium that the church used to be part of was destroyed in 1861 during anti-clerical movement, destroying the chapel of Del Rosario and Tercera Orden as well. This opened up what is now Leandro Valle Street on the church's west side.
Due to its style, the church is attributed to Pedro de Arrieta. The general style is considered to be Mexican Baroque but before the introduction of the common "estipite" column with its signature inverted truncated pyramids. The front facade is covered in tezontle, a blood-colored volcanic stone and the portal is made mostly of cantera, a white/grey stone. It has twelve columns around the main entrance, with Saint Francis and Saint Augustine on the first floor. On the second floor, a stone relief depicts Saint Dominic kneeling as he receives the keys of heaven from Saint Peter and the Epistles from Saint Paul as the Holy Spirit rises above the group. In the center at the top is a bas relief of the Assumption located between two windows that light the choir area. It is decorated on the east side with stone figures of Saint Dominic and Saint Francis. Their arms are intertwined and shown to be literally holding up the Church of Letrán.
