Starting in 1857, due to Benito Juárez's Reform Laws, many convents were closed, or continued to operate clandestinely by constructing buildings around the convent. The only contact with the outside world was through the door shown in this room.

The last exclaustration occurred in 1934 when an antiquarian reported the convent to the police. Legend has it that when the police arrived to search the houses surrounding the convent, Detective Valente Quintana accidentally broke a vase where a small bell was hidden. When the bell rang, the prioress opened the door, marking the end of nearly 250 years of existence.
