From downtown take Hidalgo street, and in its intersection with Benito Juárez street is the Núñez Garden. Surrounding it by its south part you can access Revolución street and the Temple is in the west flank of the mentioned garden.
When disappearing in the middle of century XIX the Old Mercedario Convent and its chapel of our Lady of the Mercedes Captives Redeeming, which occupied the half west of the frontal block to Cathedral, where today is the Municipal Palace, the illustrious priest José Ramón Arzac proposed and directed the construction of the new temple of the Mercy, initiated in 1871.
It is one of the few Temples in the city constructed of stone. It is said that the material was carried by hand by the faithfuls from the near stream of the Manrique, three blocks to the west. Perhaps that was the reason of the slow progress of its construction, as much, that 60 years later an earthquake threw down the cupola, when the construction had not been finished. Soon its reconstruction began, although to the same rate; so that 10 years later, when the 1941 earthquake came, it remained unfinished.
It have only been conserved of the project and its original construction, parts of the lateral walls and the facade. This is characterized for having two volumes, with the access finished off in half point arc and flanked by twin columns of doric order; the bay of access is framed with molded quarrying and a half point arc, demonstrating the key, conserves its original carpentry with reduced arc. This body is finished off with entablature with stonecutting cornice.
The second body is also flanked by two pilasters with plinth and two twin Ionian columns to each end. It preserves a window bay of the choir, with vitral, framed in put molded quarrying and bent roof, demonstrating the key, this body displays a pinnacle in a fronton way. In its ends it displays an apparent stone entrecalle (space or groove between two moldings), with an óculo in each side. The right entrecalle is finished off by a bell tower; the left one is unfinished. By Madero street, it displays in the atrium a secondary access with an iron door covered with lead. There is a well with a curbstone towards the north of this access.
