Its eparchial seat is Mexico City, where is located the Nuestra Señora de Valvanera Cathedral.

Since the 1960s immigrants began to arrive in Mexico from Lebanon and churches have been founded for the celebration of Maronite Masses.

One of the initiatives to improve pastoral care of the Maronites was made by Eparch Tayah in the translation of the Maronite Missal by its priests into Spanish, instructing the priest Alberto Meouchi to conduct a Missal and Lectionary for the altar and other prayer books for the faithful.

The eparchy was erected on 6 November 1995 with the papal bull Cum Christifideles[4] by Pope John Paul II.

Other initiatives carried out by Eparch Tayah were to remodel the Church of Nuestra Señora de Valvanera, Mexico City, current Maronite Cathedral as well as the acquisition of the Episcopal residence.
