 The cathedral has had perhaps a dozen organs over the course of its history . The earliest is mentioned in a report written to the king of Spain in 1530 . Few details survive of the earliest organs . Builders names begin to appear at the end of the sixteenth century . The earliest disposition that survives is for the Diego de Sebaldos organ built in 1655 . The first large organ for Mexico City Cathedral was built in Madrid from 1689 to 1690 by Jorge de Sesma and installed by Tiburcio Sanz from 1693 to 1695 . It now has two , which were made in Mexico by José Nassarre of Spain , and completed by 1736 , incorporating elements of the 17th century organ . They are the largest 18th century organs in the Americas ; they are situated above the walls of the choir , on the epistle side ( east ) and the gospel side ( west ) . Both organs , damaged by fire in 1967 , were restored in 1978 . Because both organs had fallen into disrepair again , the gospel organ was re @-@ restored from 2008 @-@ 2009 by Gerhard Grenzing ; the restoration of the epistle organ , also by Grenzing , was completed in 2014 , and both organs are now playable .
