Abandoned Convent and Boarding School. Rumor was it also was an Idian Residential School. Zell, South Dakota. Benedictine Sisters taught here from 1883-193.
This is the only convent and school building left standing at St. Mary's.. The catholic church associated with the convent is still standing and for sale.
Some paranormal people should investigate. Its haunted, for sure and the energy is pretty dark.
