Set in a former monastery school and chapel dating back to 1628, the museum now houses a collection of religious art relating to the Colonial period. Down below in the crypt, 12 former parishioners lie in mummified form. They were found by the Liberation Army of the South when hunting for treasure, and they left them where they lay. Now visitors can see them, laying in velvet-lined glass and wood caskets. Oh, and you can buy great tacos in the area! Fast forward to 5:28 to see the mummies.
