You have to request to see the murals by Diego Rivera at this 1600's convent now used as offices. It's free but you need to take identification which must be left at the front desk and is picked up on leaving. There are three floors of paintings between doorways around the courtyard on the lower level and on the upper two levels. The images show traditional ways, political themes, workers and more. Painted by Rivera in the 1920s, there are 120 panels in the two front courtyards. #mexicocity #diegorivera #art
