Earlier this month, workers searching for termites found two mummified bodies in a convent in central Sao Paulo. Experts believe that the mummies are around 200 years old.

The mummies, thought to be nuns, were found in Mosteiro da Luz (Monastery of Light), a monastery founded by Brazil’s first saint, Antonio Galvao, in 1774. An estimated 129 nuns were buried in the building, and experts think that the two bodies were buried at different times. Further testing will determine the exact ages of the bodies.

According to archaeologists, the bodies were preserved due to “good ventilation and low humidity.” As múmias, the female mummies, may be just two of another five preserved bodies.

The Brazilian press claims that the mummies might be featured in an archaeological exposition later this year.
