“Asilos Magdalena” is about the Magdalen Asylums, which were Roman Catholic institutions intended for the rehabilitation of “fallen women” in the 18th and 19th Century.
“Fallen women” was a popular term in the 19th-century to describe prostitutes, women with mental health issues women with a child out of wedlock, or any women perceived to be a witch.
A connotative theme in this song is the relationship of one of the women in the asylum with demonic forces and demonic possession.
