The Museum of Santa María de la Asunción, located just south of the main plaza in the center of town, was the parish church for the community from the 16th century until the mid-20th, when it was declared a national monument.
Since the discovery of Cuauhtémoc’s tomb under the main altar, this building and its grounds have been converted from a religious sanctuary to a civil one.
 Most, but not all, of its Christian iconography has been taken out.
Where the main altar used to be is now a shrine to the last Aztec emperor, with his remains on public display.
A small museum occupies the former church’s annex.
Jairo Rodríguez, son of the doctor who made the documents about Cuauhtemoc’s burial public knowledge, is the official chronicler of Ixcateopan and the guardian of the museum.
