Which city was the meeting place of the Mexican Inquisition tribunal?

The meeting place of the Mexican Inquisition tribunal was Mexico City.

The Holy Office in New Spain operated from Mexico City, the administrative and ecclesiastical center of the colony. Its tribunal was housed in the Palace of the Inquisition, a building associated with the institution’s courts, offices, and proceedings. The tribunal’s formal jurisdiction covered much of the viceroyalty, but its central records and institutional authority were concentrated in the capital.

The Mexican Inquisition was officially established in 1571 after Philip II ordered tribunals created in Spain’s American colonies. A separate tribunal served Peru from Lima, while the tribunal in Mexico City handled cases connected with New Spain. That makes Lima a nearby but incorrect answer: it was the seat of the Peruvian Inquisition, not the Mexican one.

The Palace of the Inquisition still stands in Mexico City and is now associated with the Museum of Medicine of the National Autonomous University of Mexico. The building’s survival helps explain why Mexico City is sometimes described not merely as the tribunal’s meeting place, but as the location of its permanent institutional headquarters.
