Iglesia de San Lorenzo, New Spanish Baroque church in Mexico City, Mexico

The iglesia de San Lorenzo is a Baroque church building in Mexico City with an ornate stone facade. Its structure displays geometric patterns and decorative details characteristic of colonial religious architecture from that era.

Founded by royal decree signed by Philip II on 14 November 1598, the convent and first church were sponsored by María Saldivar y Mendoza and Santiago del Riego. After flood damage, the church was rebuilt between 1643 and 1650 by architect Juan Gómez de Trasmonte. Repairs from 1779 to 1785 by José Joaquín García de Torres replaced the wooden ceiling with masonry vaults and a dome, and added the current facade. The bell tower collapsed in an 1845 earthquake.

The church keeps two 18th-century wooden pieces: the main altarpiece, carved and gilded, and the carved pulpit. In 1954 the Basque priest Ramón de Ertze Garamendi began a restoration with architects Ricardo de Robina and Jaime Ortiz Monasterio and sculptor Mathias Goeritz, who made the apse relief "La Mano de Dios" and the blue and yellow stained glass.

The church is accessible by several public transit lines that serve central Mexico City. It helps to visit during daylight hours to see the facade details clearly and to encounter fewer crowds inside.

During the 1954-1955 restoration led by Basque priest Ramón de Ertze Garamendi, sculptor Mathias Goeritz made the relief "La Mano de Dios" in the apse, modelled on the hand of Christ in Matthias Grünewald's Isenheim Altarpiece, plus blue and yellow stained glass in the windows and abstract dome glazing on the life of Saint Lawrence.
